My daughter is going to be 2 at the end of February. She won't drink out of any sippy cup. Even just cups with straws. She has no problem drinking a juice box. She still drinks milk from a bottle in the morning with breakfast. At the naptime and bedtime, she uses the bottle for drinking. My question is should I keep allowing this? She'll eventually drink from a sippy cup? Else should I gradually take it away altogether and let her cry? I'm just worried she won't drink any milk if I stop giving her the bottle. She'll drink a juice box again and again. She also drinks water but only from her bottle. Please give me useful tips. She is my first child. I do not know how to change her this habit.
