Hi G.,
My daughter is 22 months and I can't image her going to sleep without breast feeding! I've read the other mommy's replies and now have some ideas of how to wean our little one. Thank you for asking the question!
I wanted to say, don't feel bad for "giving in". I think it's important to remember that it's a relationship between two people, even though our children are small. If your son is that upset, then maybe it's not time to wean or another approach is needed. Or perhaps he feels that you are not completely ready, either. But I commend you for listening to your son's needs, and don't feel badly for taking a break and not forcing the issue.
Our daughter goes to sleep easily with our babysitter (at least that's what she tells us!), so I would guess that if someone else can help put your son to sleep, that might be a good solution.
Good luck! I know we should wean soon, too. I was hoping to just make it to one year, but I honestly don't think I'M ready to wean yet even at 22 months!
H.
