"Mommy, I like your head."
"Well thank you!"
"Mommy, you like my head?"
"Yes, I like your head very much."
"I can't take my head off" (tries to lift head off neck) "It's stuck."
"Honey, you're not supposed to be able to take your head off. It's supposed to be there."
"I can't do it." (sulks, pouting)
"Maybe when you're older you'll be able to." (this is my response to most things she says she can't do...)
"Yeah. When I get older I take my head off. Mommy, when you get older, you take your head off?"
"Yes. When I get older I'll be able to take my head off."
