Why is my daughter doing this?

[Christina86]

Hey! Ok so I have an 11mo who is now fully using the bottle. I bf for 6mo and it just didn't work anymore after I went back to work and she got teeth- she's a biter. She transitioned just fine as I was also supplementing w/ her. A few weeks ago she started climbing up on me, hitting my boobs, grabbing my shirt and trying to latch. It started about the same time I found out I was pregnant. I don't know if that means anything. I just am at a loss for why she randomly started doing this. She's never done it before. She never even really grabbed like that when we were bf. I think only time she smacked my boobs was when she wasn't getting enough fast enough. Thoughts?
