I hear this one mulitple times a day:
"Mommy, is Oliver okay?" He has anxiety.
"Mommy, is that one chocolate?" referring to my, uh, chestal area, which is currently on display 15 times a day...
"Mommy, can I watch a movie?" also heard multiple times a day.
"Mommy, can you tie this?" asked often, when he needs me to tie (or untie) a string/shoelace/rope/string/twine, etc to a small toy, so he can swing it around, no idea why.
"Mommy, can I have a sip of your soda?" one sip usually equals MANY.
"Mommy, can I kiss Oliver?" usually asked while Oliver is sleeping.
Henry likes to ask questions. I think this is normal for three year old boys... I hope so anyway.
