A Mom just wants to know

I have a few questions about the behavior of my kids. I'm sure there are other parents out there who are wondering the same thing.

~Why is it that Gia loves to suck on the nozzle of the Windex bottle (yum), but can't stand the taste of sherbet?
~Why, even though we have a play room, are there toys in every room of my house, including the bathroom?
~Is it just a coincidence when the kids spill something really big and messy on the kitchen floor the same day I mop it?
~Why is it that when I want them to tell one of their Grandmothers what they learned to say or do, they suddenly can't do it? Really, she said it just a minute ago, honest!
~Why is it that Tia can do everything by herself, except when I have both hands full and am in the middle of something. Only then does she need my help!
~Why would Gia rather play in the pantry than with her toys?
~Why does Gia poop right after I change her diaper!?
~Why are they not interested in an item until someone else wants to play with it?
~And the question I am still asking after months and months...why does Gia insist on throwing her food on the floor, and putting apple sauce (or yogurt, oatmeal, etc.) in her hair?

I'm sure I'll have more questions like these, and I'll probably never learn the answers. But, I just had to ask!
