Katico, try not to worry about it too much. life is different when another parent (or grandparent or special grownup) is around. DD can tell the difference too. She won't learn OR unlearn behavior in just one day. IME kids go in and out of these really unpleasant stages. My second is MUCH mellower in general, but even she has her days.
Other people's bellies: my DD (2y4m) has been talking about daddy's belly, and daddy's "namnies" (breasts) too. (he got here yesterday morning to pick us up. She is so thrilled to see her dad, he's only had 3 weekends with us all summer). He is not HUGE, but not svelte either. And she keeps saying, "there is no baby in daddy's belly, and daddies don't have namnie (milk)." And just talking it up quite a bit. ironically, I am on a really strict diet pregnant, so sorry, DH doesn't have an excuse of "sympathy" ice cream or what have you (I suppose his big excuse is missing us this summer??). She also recently said, about her own belly, "I don't have a baby in my belly... I don't think so" which is a revision of earlier statements. In fact, she is growing so tall this summer, her little toddler belly is disappearing!
we're driving back to NYC tomorrow. transitions. I am looking forward to it, and dreading it too.
I will weigh myself for the first time in 2 months also. A little nervous that its going to be a shock!!
okay have to go pack.
