My baby is nearly 13 mo and we tried to get her to drink her milk from a cup this morning and she just wouldn't so we caved in and gave her her bottle! Not good. She has two bottles a day, the next at bedtime and was using tommy tippee first cup with a spout for her water until a week ago when we changed to munchkin 360 where you just sip to draw the water out. She is fine with it for water but wouldn't drink her milk from it this morning.We tried keeping everything else same , holding her in arms but still wouldn't have it. Any tips on this transition or do we just have to go cold turkey and sit there TIL she takes it?
