I'm now 21 weeks and nursing my almost 3yo.
Sometimes it drives me nuts. The worst is during the night when I sleep while he nurses and then I wake up from random pain and react by pushing him away which makes me feel awful. It's not his fault that I hurt, but when I just suddenly wake up I don't realize immediately what's going on, so my self control is very limited. To make things worse, lately he's been really clingy at night and wants to be constantly next to me. If I try to move away or get up, he sits up and cries. He understands that I don't like it when he nurses, so sometimes he will ask for it and then turn away and say "no" or just hold the nipple in his mouth without actually latching on which feels weird and I'm scared that he may bite me if he falls asleep like that.
And then at other times it doesn't bother me at all. He could nurse for hours and I'm fine. I'm definitely sending him mixed messages and he's learning early that women are just hormonal messes and you never know where you stand with them.
I'm hoping to tandem nurse when the little one is born, but we'll see how it goes. He may just give up before then or I may push him away for good. I would like to get that bonding between him and the baby, because he tends to be jealous if I play with other kids.
