It is definately possible for them to have too much milk. I had to battle this problem with my second child. She wanted to drink instead of eat. I would definately keep to your doctors recommendations. Children get dairy from so many foods. There is far more calcium and nutrition with no ill effects from foods like fresh peaches, leafy greens, nuts (when she's older), legumes, oranges and more. Filling up on milk (which nutrients the body does NOT readily absorb) prevents children from eating other important foods in their diet. Milk is sometimes referred to as "liquid protien." The protien in milk gives your child a sense of being full which decreases her appetite.
I had to take milk completely out of my daughter's diet to get her to eat. It was difficult on both of us. She also liked a bedtime bottle. She has the worst teeth of all my children. Please don't allow you daughter to go to bed with a bottle. Save yourself and your daughter hours of dental work and hundreds of dollars. My daughter, now 8, has had to have fillings redone (ouch! twice) and a tooth that had a baby root canal gone bad extracted and a spacer put in. This daughter was a terrible sleeper, so I understand wanting to do whatever it takes to get her down. At one, my daughter refused to nap (and I tried everything), and woke 3x's a night for almost three years. I discoved at the end of her second year it was due to apnea, which was corrected surgically. If she needs a bottle, fill it with water and stick to your guns. She will eventually either take it or go without. Protien causes alertness/wakefulness, so it could be the mild that is helping to keep her up. A bowl of cereal or pasta before bed would be better. Carbs can help you feel satisfied (especially whole grain) without effecting sleep.
I have two other daughters who will require orthodontics due to excessive pacifier use. My pediatric dentist said if they start sucking on their fingers, let them have a pacifier. If not, try to break the habit by one year of age. I'm currently having to break my almost three year old from the pacifier and it is extremely frustrating for both of us.
Milk is in reality not a dietary necessity. Our culture has been brainwashed since the 1940's-50's to believe milk is essential for good health. It is simply not true. So don't feel bad cutting back your daughter's milk intake, you'll be doing her a favor. My five children do not regularly drink cows milk (they get it at grandma's house) and they are healthy, bright, and active. Best of luck to you and enjoy your one year old! Its a great age, I have one too.
