Yes, what Lou said and your daughter is having to share you with a peer which is different from a sibling. That is probably the reason for the pushing. You have two little ones experiencing new stages in their lives at this stage in their development. I would respond to your daughters pushing with a definite no, but also give her hugs to let her know her position with you is secure. Then I would include dcg and daughter together with you in an activity so the girls can get used to each other and watch how you interact with both of them. Hope this makes sense, I just woke up.LOL
