My ds breast fed until 5 months, and has also taken a bottle since birth, with no problems.
Now he is formula fed, and has started solids, but is not interested in taking water or milk from a sippy cup.
He still drinks a fair amount of milk, and has 150 ml in a bottle before his solids, so I'm not convinced he's actually that thirsty.
Do most babies drink out of a sippy cup at that age? What did yours do?
TIA
