It's great that you're aware she's trying to make up for lost time, that sounds exactly like what your daughter is doing. If you're finding that you're full, is it possible for you to pump at work and then have her drink the milk while you're gone? I know that won't make up for the bonding, but it may help.
I've been reading about weaning lately too, because I have a 2 yr old ds who nurses frequently, and I don't want to wean, but I do want to cut down. I have read that when your child wants to nurse, and distraction isn't working, that is a sign that they truly need it. Sometimes older children ask to nurse so they can connect with you, other times, though, they really, truly need to nurse. Maybe you can start with small steps. When she comes to you to nurse, suggest that first you want to read her a favourite story (or do a short play like row your boat or the itsy bitsy spider). Then, when the story is done, she may still want to nurse, and that's fine, but she may learn that she can put it off for a few minutes, and over time, those minutes will grow. If she freaks out at the suggestion of a book first, I'd lay off, but if she's receptive to it, it will help her learn that there can be more to her relationship with you than just nursing. Also, since you've *just* returned to work, it's very likely that she is still adjusting to that major change, and after a few months, the new routine should settle.
