Who is unreasonable, me or DH?

I would say its very unusual to not have had more than an hour away from your 7 month old. It really doesnt sound healthy to me but its no one else's business (obviously you've asked on here but I wouldn't comment in real life)

Yes, it's normal for Mums to spend more than one hour away from their child in 7 months. Very very normal. Even when they're on maternity leave. I mean, you do you, but it ain't normal and the sooner you break this habit of dependency on your child it will be better for both of you.

You do what’s right for you, the person who’s bought the tickets should understand and your DH.

Yes, your behaviour sounds very suffocating and may provoke separation anxiety. You say yourself that you didn't behave this way with your other child.

At what point do you plan to leave her with your husband and do other things occasionally?

With kindness
this setup isn’t helping DD she only you as care giver
DH must feel pushed out and not trusted
your other 2 DD are missing out

YABVU, I feel for your older children.

How old are your other two DD's. If they are still children/ teens, when do they get time with their mum , as the priority?
Your dh must feel like a spare part, he's not being given much of a chance to parent .
I suspect your dh doesn't think this is a healthy dynamic for you, baby,'him or the two other DD's.
Which is why he's keen for you to go out with a friend for a few hours.

The longer you leave it, the harder you are going to find it to have time away from her at all. Bite the bullet now or it'll be you sobbing your eyes out as she goes to nursery, as well as her who will be too dependent on mummy 🙁

What’s different though? Why do you feel clinger to this baby? What’s changed?

same father for all? Big age gap? Final 100% baby?

Whats making her your world?

How are your other daughters.

You are being unreasonable yes, I do empathise with you though. 😊

I'm going to be honest I know two people who behaved like this with their child and both eventually sought professional help for postpartum depression. Although not before one of them had a relationship breakdown because they didn't want to seek support and wouldn't allow their partner to parent his own child alone.

It really isn't typical behaviour and I'm wondering like others how you can't see that this, especially because you have another child whom you did leave. I do wonder if the gender of the baby is the difference here.

My advice would be to seek support asap and recognise your partner is trying to help.

I have to say, I think many mothers get selfish, and think they own their child. They want their child's love only for themselves. They don't even want the child to be with other people.

When it is actually good for a child to spend time with other people.

He can fuck off insisting. It’s completely up to you. I didn’t like leaving either of mine at that age and wouldn’t have for something like this. They have fantastic relationships with their dad. I bf and at 6 months one didn’t really do solids and wouldn’t take a bottle.

How’s your relationship with your other child, do they live with you?

my first child was nine months before I had a couple of hours out in the evening. We are all fine and well adjusted. My three are all adults. I’m glad I spent that time with her. I wanted to.

Is the other DC a boy?

Both of mine stayed with my mum about once a month from 8 weeks old. I would have gone insane otherwise. I also did KIT days and the usual stuff of going into town or to get my hair done without them.

To me your level of attachment is baffling tbh, but if it’s how you feel it’s how you feel.

I’d worry that you’re excluding DH from bonding with her though, and your other kid(s) must be needing your undivided attention sometimes.

Yes I had left both mine with either DH or my parents by the time they were 7 months, I was still breastfeeding then both times so wouldn’t have been for 5h but definitely more than an hour

You sound unreasonable and overly clingy OP. Your child is an independant person. Your child is not an object that you own. Let the child be with other people

I have to ask you this - were you loved as a child?

My mother wasnt loved as a child.
When she became a mother to me, she saw me as her only source of love, and she became extremely clingy of me

She wouldnt let anyone else look after me as a child. She was clingy. It made me want to get away from her. And now I am an adult I moved far away from her to have my own life

Yes I had 4 months mat leave 22 years ago, I had no choice, so DS went to a childminder twice a week.

I think it’s also very normal for Mums to have a hour for a swim, or a run or even a nice bath! It’s a lovely gift and perhaps your DH would like quality time with his DD?

YABU because this sounds quite extreme, no reason at all why you can’t leave a 7 month old formula fed baby with her Dad for 5 hours.
Why not start small and plan some outings over the next month to get you both used to it?
Leave DD with DH and go to the shops/for a walk/for a coffee

Does he get to look after her at all at home?

I felt much the same as you with all of mine, but it would have done me good to be sent on my way. I was BF though so a little different

What’s the difference between this baby and your other/s? Why so clingy this time around?

You should be able to leave her with her father and siblings for a few hours.

In fact dad should be able to have a few hours with his children without you anyway this isn’t a separated ex who barely knows his baby this is your husband who you live with.

I think making you feel forced is the wrong approach but I don't think he's wrong to encourage it. I also think that it's important to respect and nurture more than the singular relationship between you and your youngest... the relationships between baby and her father and with other close relatives as well as your relationships with your husband, other child(ren), and other family and friends are all deserving of that.

How much time have you had one-one with your older child(ren) since your youngest was born? With your DH? How does DH feel about the opportunity he's had to bond with the baby and tend to her needs without you getting involved? Do you know what's going on in the lives of your family and friends right now, and how they're doing?

From baby’s perspective: it would be good for her to have a little awake time away from you and with her other parent. It’s just a few hours (given naps/ bedtime etc).

From DH’s perspective: she’s as much his as yours, he’s quite capable, let him have her. It’s just a few hours.

From your perspective: it’s interesting that this baby isn’t your first and you weren’t like this with the other child. Is it too nosy to ask why you feel this way about this baby and not the other? I’m semi-scared of the answer, and think it could be why you’re feeling the way you do. The answer could override all the above and totally change my answer.
