Re: Getting DH "on board"
I think in your shoes I might stop asking for your DH's input on the subject of nursing past a year. If you keep asking him what he thinks you should do, you may be giving him the impression that he gets to make the decision. It's like wanting pizza for dinner and then asking "Honey, should I make pizza or tacos for dinner tonight?" If he says "tacos" and you not really enthusiastic about making them, then all you did was give him the false impression that he was going to be the one to choose what you had for dinner. If you just said "I'm making pizza for dinner tonight, set out the plates," he might just say "Okay."
The other tactic to take would be to really delve into the discussion, and ask him why he thinks you should stop nursing at 1, and why you should push solids now. Does he think that nursing will make your child overly dependent on you? Does he think that babies "need" more nutrition than breastmilk can give? Does he feel that your breasts are actually his breasts, and he doesn't want to share them with the baby?
