Eli vs the sippy cup

So on Saturday we decided to take the bottle away. Eli has been drinking water out of a sippy cup since he was 6 months old and transitioned to cow's milk beautifully. He did great the first day, yesterday was a little worse, and today he is acting like he has no clue what to do with the straw cup-- he keeps blowing into it. He is determined. He was playing yesterday and Ryan said "bottle" in a sentence and he threw down his toy and RAN to Ryan crying "bot bot, bot bot!" Poor baby's heart was broken when he realized daddy meant sippy cup. Momma's staying strong, but so is Eli. We might have a battle of wills going on for a while.
