I had a rough childhood, with an emotionally abusive stepdad who my mother never protected me from until he died when I was 13. My mum had a daughter from that relationship who still lives at home with her own son who is 4. I have a 2 year old DS and am pregnant (due in July). My mum has always been quite unreliable, is always late, and is very disorganised. Our relationship has survived the horribleness of my childhood (lots of therapy), although there will always be that part of my mind that doesn't entirely trust her.
I moved closer to home when I got pregnant because I wanted her to have a good relationship with my DS. She loves him to pieces but continually lets him and me down when it comes to spending quality time with him and giving me a much needed break. This stings because she spends inordinate amounts of quality time with her other grandson, and their relationship is very special. She is basically his primary carer as my sister is emotionally unstable and also rather verbally abusive herself.
My mum told me that she would take time out of every Tuesday to spend some time with DS. She persistently turns up late, or calls and cancels, or brings her other grandson with her, or even my sister, which I really dislike as I don't want my DS exposed to her temper tantrums. Yesterday she txt me to ask if my sister and DN could come over because she was feeling sad and didn't want to be on her own (she is very emotionally messed up herself, for which I am sorry, but her problems have been ongoing for years and are getting old - she isn't too sad to go out every night leaving my mum caring for her son). I lost it. I asked her to call me and explained that this was meant to be special time for her and my DS, and that I was pretty tired and needed a break, not a house full. We fell out about a similar thing a couple of weeks ago when she took her other grandson out to the theatre on a sunday afternoon without even considering taking my son too. She can carve out 'special time' for one but not the other.
I feel I need some support at the moment, my DH is poorly and has just been put on steroids, his family is very flaky and there have been some issues there recently, and I am pregnant and tired. She basically told me she cannot commit to the time she offered. She works part-time but has too much on at home caring for my sister and grandson to come over regularly.
Sorry this is so long. I guess I'm just tring to figure out what to do next. I am meant to be giving birth at home with my mother caring for my DS, but I don't think I can trust her to be reliable at that time, and I have no-one else to turn to. I can imagine giving birth to an audience of my mum, my son, my sister and my DN (oh and my mum's dog) because she has absolutely no respect for my boundaries. I just feel like giving up on her at the moment.
