My daughter is 2 yrs old and my family doctor suggested I get her off of her bottle at this age. She wants me to offer milk in a sippy cup, but my little girl won't go for it. She said they don't want them on the bottle longer than 2 for risk of tooth decay, but also don't want me to take milk away as it contains fats which are important for brain development. She told me it was my call. What should I do?
