YABU - as you are judging yesterday's parenting standards by today's. Lots of parents were neglectful and abusive by today's standards.

YANBU - No parent should use their child(ren) as an excuse to stay together and then say it to them, unless they want to risk fucking up their mental health and damaging their adult relationship with them.

You can't help your feelings.
I wouldn't say they were neglectful to a massive extent. I know you said they left you without dinner and you made yourself instant noodles, not the best but it means there was food in the house.
Staying at your grandparents was probably the best decision at the time if they weren't in a suitable emotional place to give you what you need.
It's not ideal, and there is no way I would treat my kids in a similar fashion. I could be biased as I think childhood was pretty bad, I haven't forgotten any of it but I am also aware that still alot more childhoods were worse than mine.
But you feel how you feel, you can't change that, you can't forgive and forget what happened if you're not ready to.
And sometimes low contact is probably better in these scenarios.

That behaviour was not acceptable then either. Your parents disregarded your emotional well being (and arguably your physical well being too).

It is worth remembering that it's never unreasonable to feel something - only to act unreasonably based on a feeling.

It's up to you whether telling your parents about your anger would be useful for you or not. Something tells me their reaction might upset you further. You say they are distant and disinterested in your son - dost you expect them to change?

Sorry about your shitty parents.

I'm sorry that you're going through this. I, too, have felt resentment towards my parents after my DD was born.

I think the best way to ensure that you do things differently. Don't make the same mistakes. We're not perfect, any of us. The most important thing, though, is to be the best parent that we can possibly be.

I do NOT agree with PPs who said it was more normal back then. And noodles were fine for dinner?! ON XMAS DAY.

I'm sorry your parents were like this. I'm not surprised you're resentful towards them now. It may help to talk out your issues if you can afford counselling.
It wasn't normal, or acceptable and you know this because it sounds as though you're doing the complete opposite and raising your DC well. 

They sound terribly selfish OP, I’m surprised people are minimizing it - it sounds neglectful to me even by “yesterday’s” standards. My mother would never have done any of that and I definitely don’t think it was “normal” assuming you were born in the 80s? I’m not surprised you’re resentful. Not sure what you can though though other than ensure your DC get better parenting than you did. Try not to let it make you bitter - that’s wasted energy and their shitty behavior doesn’t deserve your energy

onename at least by being distant they are not exposing your child to the feelings of abandonment you must have experienced. And you know you won't do that to your son.

They were and still are terrible parents. Just because other people had it worse it doesn't mean you're not allowed to feel you also had a less than ideal childhood.

You don't owe them anything. I think it's probably a good thing they're not inflicting their dysfunction on your innocent little child.

Wtaf that pp are trying to justify this.

I also thought my crappy childhood was normal until I had my DD and thought 'but I would never treat her that way...'

I'm sorry your childhood was so poor. It sounds lonely.

My df parents were shit as were my fil abusive affairs etc but they ensured that when they had children they focus on been a better parent than they had. They aren’t going to change op but you can ensure you’re a better parent to you’re children.

Your parents were abusive. That's not acceptable now, nor was it previously.

You definitely got the shitty end of the stick OP parents wise, and GP too, I mean who is too old to cook! (unless your in a care home). I'm just surprised it took you this long to realise that your childhood wasn't normal.

It is completely normal when you become a parent to review your own childhood and negatively judge your parenting. It is a big part the the process of deciding how you will parent. I remember being disgusted at some of my parents behaviour, specifically my Mum’s smoking. A lot of that reflection tend to be on what you will not do.

But your childhood was not acceptable at the time. There is definitely much more of a focus now on being a good parent where as the parenting I received in the 80s I think was much more of just plodding now and less reflective and less concerned with the potential impact on children. Again this does not justify their behaviour.

OP yanbu. I'm surprised that some posters are minimising your parents' behaviour.

FWIW a very similar thing happened to me. At 9 months pregnant I felt a surge of anger towards my mum for the violent temper that she had filed me with as a child, and for having alcohol issues that horribly affected by childhood.

Prior to being pregnant all this stuff was stored safety at the back of my mind. I was proud of myself for not letting it affect me very much as an adult.

Something about impending parenthood bought everything flooding back in Technicolor. As DS has grown up I've become more secure in the feeling that my mum made my life as a child very unpleasant and frightening at times.

Sending you a big unmumsnetty hug.

Can’t believe the first few responses! That’s properly shit parenting. YANBU at all.

I agree with you as I have been through the same process. And for me it got worse as the DC grew older and I realised more and more how unpleasant my DP were. What I hang onto is the idea that their crap parenting has made me a much better parent that I might have been - I take nothing for granted. My motto as a parent is 'be kind' - there was not much kindness in the house I grew up in.

I agree with posters saying that the positive effect of this is that it allows you to consciously parent in a different way.

Interesting to read the poster who was bought up without much kindness saying that her parenting motto is 'be kind' .

My overriding feeling was that had no one strong to lean on as a child, everyone was drunk, or busy or angry so I had to be the adult. As a result my parenting motto is 'be their rock'.

Sorry OP, that does sound like neglect Most of my friends who have had children have found they have become much more grateful to their own parents since becoming parents themselves as they see how hard it can be and realise how much effort and sacrifice their parents made for them.

You’re having the opposite experience and it must be painful. As others have said, try not to dwell on it as it will be a waste of your energy. Better to try to accept the situation for what it is and ensure you don’t follow the pattern. You sound lovely so I’m sure you won’t and it’s probably better for your baby to have limited contact with your parents anyway.

Conker I tried not to dwell on this type of thing but it became very difficult to ignore.

Counselling helped immeasurably.

@BlueBug, I disagree! YABU - as you are judging yesterday's parenting standards by today's. Lots of parents were neglectful and abusive by today's standards.

Abandoning kid for days so that GP had to contemplate calling the police. Being too hungover to be with the kid on Christmas Day. That's not 'yesterday's parenting'. That's neglect.

OP, you have every right to be hurt by this, and I agree that once you have your own children you look back on things with a different perspective.

I feel like your GP were just as neglectful tbh. Unless they were 89 and couch bound I don't see how they would be 'too old' to cook

I agree with the counselling idea. Not dwelling on things (I.e. repressing them) tends not to work out well in the end.

I think it's quite normal to have these feelings OP but if you don't know what to do with the feelings counselling is a good route to take.

Some people are just not cut out to be parents, they are too selfish and self absorbed to put their own wants second to their child's needs. Sadly, its not until they have had a child that his becomes clear.

YANBU to be pissed off with how they neglected you.

As my children grow up I definitely find that I have less understanding for the poor behaviour they displayed to us children BUT you need to forgive (not forget) for your own sake and move forward from it.

It doesn't make it ok but it lets you live your life free of the resentment that you would have if you chose to hang on to the anger rather than forgive.
