We got a new sippy cup for #3 (4.5 yrs old) upon many repeated requests.
As she was opening the packaging, there was a little piece of paper inside of the cup. She asked #1 (9 yrs old) what the paper was for and it went down like this:
#1: It's instructions for the sippy cup.
#3: Wow! "You Put Milk In It" is the longest word.
