I'm pretty certain that we will only have one child - he is 2.5 and HARD work.....albeit lovely, funny, cute etc!
I know my limitations, I know how much I enjoy peace and quiet and my own headspace, which I get rarely. I want to go back to work when he starts school, our lives are finally starting to get a little easier. Having another baby would propel us backwards and I know I would resent it.
Having said all of that, I STILL seem to get these twinges of sadness that he won't have a sibling, that perhaps I could do it all over again. I was in tears packing up his baby clothes! It's a head fuck. I do think that my feelings are intensified because society deems 2 children to be the 'norm' but what if 1 child was considered the norm, would I still want another? I don't think I would, I would feel happy and vindicated in my choice. So I have to keep reminding myself of that.
Secondly, the social media aspect. Seeing all these snapshots of siblings cuddling/playing etc certainly pulls on the heartstrings but that's all it is - a snapshot in time. All the people I know who have 2+ kids tell me about the fighting, competing for parents attention, that it's more than twice the work, the exhaustion and stress that the parents feel. That is the reality that's not projected on social media because nobody wants to talk about the bad bits. Only behind closed doors!
Out of my NCT class of 6, only one other person wants another one. One child families are so common these days, not in the majority yet but fast forward 20 years and I think it will be.
To the OP, did you say your daughter was 9? That sounds like a great age to me! I'm going through toddlerhood right now and it's no joke. It's bloody exhausting. Do you really want to go back and do it all again now? As time passes you forget just how difficult, stressful, exhausting and all consuming it can be. The grass isn't always greener.
There are so many different paths in life. Some people have one, others have 2, others have 6. Some people choose not to have any, some can't have any. There's always something to feel guilty about it or to question our lot in life.
This is obviously something that weighs heavily on your mind but ask yourself, are your feelings of sadness primarily because your daughter won't have a sibling? Or is it because you want to experience motherhood again? If it's the former then honestly, your daughter will be fine, there are so many pros to being an only child. If it's the latter then that's a different story, but you need to either, go for it and have another or make peace with what you have and start looking forward.
All the best whatever you decide
