Sibling rivalry

I think my kids had a fight today. Well, Bianca did, but Deuce kicked back! Bianca and I were sitting on the floor in her room, and she gave a hug and a kiss to her doll and then to me. I asked her if she could give a kiss to the baby, and she said "NOOOOOOOOOOOO!" Then instead of lifting my shirt to pat my belly like she usually does, she started pinching it and pushing it and yelling "MYYYYY MOMMMMMYYYYYY!" Out of nowhere! And yes, there was some kicking on the other side too. I put a stop to her outburst right away, and of course she can't explain her behavior. It was almost funny--now I know that she really, truly, 100% understands that there is a baby coming out soon, and that she's going to have to share her mommy. At least she's dealing with it now! Later on, she came over and kissed and hugged my belly and said she loved the baby. So I guess they're good--for now!
