DS is 9mo. He can hold and drink some water from his tommee tippee sippy cup although much goes on the floor. He takes a bottle from me in the morning, aternoon and at bedtime. How do I move onto giving him milk in a cup and is the tommee tippee one ok? He gets gaviscon in his milk so is this still ok? He is really sleepy at bedtime and I don't see that time working just yet. I am also worried about the mess, it's expressed breastmilk which is terrible for getting off when it spills.
