Oh, boy! When my son saw me holding his sippy cup walking away from him he went off crying. He thought that I forgot to give him his before bed time milk. He likes to drink milk before either taking a nap or going to bed at night. He even asks for a cup in the morning before breakfast. When I went to our room to give him his cup he stopped crying to say thank you and took the cup from my hands as fast as he could before I change my mind. He is a funny little boy sometimes. And I love him so much.
