That is what Julia told me tonight when I asked her why she did something. I don't even remember what it was that I asked her, but she responded with "Cuz want to." Can you guess where she picked that up? Her sisters. She also picked up "why?" She's 19 months old and has been using those phrases for a while now. Cassidy didn't start asking why until almost three years old, than Molly and Julia picked it up real fast. I have three little girls always asking me "Why?" Gets old after a while, but "Cuz want to" is way cute.
