Tah tuh

Often when I change Morgan's diaper he requests a bath, by saying, "Tah tuh?" Bathtub. He loves his baths. When it's time to wash his hair I lay him down in the tub to wet his hair and rinse it. He didn't used to like this part at all, but lately he has resisted when I go to pull him up. He likes just lying in the water even though he can't really turn his head one way or the other since it would result in an eye/nose/mouth full of water. He doesn't really know how to get up though.
