"I.... do.... it.... MYSELF!!!!!"
Sure, you think that is all cute, but it is not cute whenever we are trying to get somewhere, which is. all. of. the. TIME!!!
Actually, I exaggerated a bit. He only does this 50% of the time. The other 50% of the time is "Mommy **YOU** DO IT!!!". I don't know which is more "challenging".
I guess that is what being 3 is all about.
Good thing he is so gosh-darn cute.
