Girls need help, my son is 3 years old but he still drinks water from his bottle even when he sleeps at night. He hugs his bottle and drinks lots of water from it ??‍♀️??‍♀️He drinks water from a glass, but says "fill up my bottle" ??I didn't give him a bottle this evening. He asked for a bottle and cried a little bit, but explained that the bottle was bad and I threw it in the trash. Do you think I am doing the right thing? Or should I keep giving him a bottle?
