Thank you for the replies and the support. I'm feeling pretty low about it TBH.
Basically DH wants to wean completely and he recognises that the nights will be the hardest to do (for us at least). I don't understand all the reasons why he wants to wean, as we've only talked about it once, but TTC is part of it. I think he also feels that if we don't stop soon, it'll go on forever, and if I do get pg again, it'll be difficult to wean then (from which I guess he's not overly keen on the idea of tandemming).
DS has also just had a difficult spell when he was asking for milk about a million times a day, and getting really upset unless I offered it, but then not really wanting it most of the time. I was tired and upset and got shouty with DS which made it worse. However, the first of his last set of molars has come through and all that has stopped, so things are serene again - but I can imagine that DH might see bf as a problem making DS be more demanding and me be more cross.
I don't think DH has ever 'liked' bf - he's never been unsupportive, but has said on occasion that it 'makes him feel funny' (he is really, really squeamish about pretty much anything at all biological). I think DH has 'put up' with DS bf'ing past 12 months because it made our lives easier (& especially because DS used to be an appalling sleeper), but now he wants wean by the time DS is 2.
I'm a SAHM and rarely have any time away from DS - my last whole day away from him was in January! However next week DH will be looking after DS during the working day Mon - Thurs while I go out. He said that DS will have to manage without bf then, so he should be able to manage without on a normal week. I don't think it works quite like that, but I can understand why he thinks that.
DH wants to day wean first and then think about the nights. I don't think DS is ready - he wants milk when he's in pain or upset about things. I don't relish losing my tool for calming both of us down and I'd like to keep going with all the other benefits of bf for a while at least. Also I suppose I 'still' bf DS because I love him, so the idea of stopping bf makes it feel like not loving him IYSWIM, although I know it doesn't mean that really. :(
DH knows he'd have to do all wakings while we night wean. I don't think he appreciates how hard that could be for him (depending how it goes). He's had insomnia in the past so doesn't sleep fantastically anyway. I suspect that once weaning was over, I'd have to keep dealing with nights. DH wants to wean by Christmas and he'll be re-starting part-time work on top of full-time studies in January, so he will be very busy & very tired from then on. In theory I can nap during the day to make up for nights, but in practice I find it really hard to nap unless I've fed DS first (helps me to sleep as well as him!)
I doubt that stopping night feeds will improve DS's sleep much. It might persuade him to cut out his usual wake up at my bedtime, which doesn't bother me (and about once a week he sleeps through anyway, so he's moving in the right direction). I can't imagine that it'll have any effect on the developmental type wakings though as about 50% of the time then he needs rocking/patting back to sleep after he's fed anyway, and those wakings always stop once the developmental leap or teething is over.
I really don't mind doing night feeds nowadays - it's easy to deal with DS without having to get out of bed. I don't really want to stop co-sleeping either, but I can see that I might have to. Bedtimes will be harder if not feeding to sleep - DS will be rocked to sleep, but it doesn't always work. I don't think he's ready to properly self-settle yet, and when he does sort-of-self-settle at bedtime or naptime, he wakes much more often than he does if I feed him right to sleep.
I've told DH I'd like to discuss it more and he suggested I found out about other people's experiences of night weaning so we can talk around that now.
I've stopped offering feeds on waking and with a small amount of distraction DS hasn't had the feed on waking from his nap for about 4 days now (to my amazement). Distraction doesn't generally work for him though and definitely doesn't if he's upset.
Sorry for the eassy , it's a relief to get some of this off my chest.
