Why does your husband want you to wean so badly? Just because they're "his" boobies? :)
Honestly, I think you have the right idea, and I would be very insistent with my husband about the issue. There are a million reasons why it's good to nurse past the age of one, especially considering the specific circumstances. Does he have to put her to bed? Is he willing to share this responsibility when it comes to putting her to bed without nursing? Because she may be very upset about the sudden change.
I mean, I can list off all the reasons why I would give it a little more time if I were you, but I think you already know why it's a good idea. If you'd like more specific info though, feel free to email me. (I'm in nursing school, going to start working on my lactation consultant certification soon, have read books and anything else I can get a hold of about breastfeeding, and still nurse my 18 month old before bed when he wants it.)
I personally don't understand what it is about the magical age of 12 months that people think every child is ready to wean on their birthday. I doubt your daughter can read a calendar, and does not care when your husband thinks she should wean. Every child sits up at a slightly different age, rolls over, crawls, walks, eats, talks, and weans at their own time. Trust me, on my son's birthday he was still nursing 5 times a day, and I was afraid I'd never get him to let up. By 14 months he had self weaned down to 2-3 times a day, and by 15-16 months it was pretty much once a day. So just don't rush it, and follow her cues, and enjoy this time you have together. Before you know it, she'll be demanding you drop her off down the street from school so her friends don't see you two together.
As far as your husband goes, I would really discuss your concerns with him, and explain all the benefits of continuing to nurse. At the end of the day, they're your boobies! You're the one that has to hear her cry if she wants to nurse, and you're the one who has to go through the drying up process (which has been so gradual for me, I haven't even noticed it because I've let my son wean at his own pace).
If you have any questions or just want to chat about it, feel free to contact me.
