My 3 year old DD tries to only drink milk.

This is after I weaned her off cordial & juice. I don't buy cordial at all anymore & buy bottled water, coz they find water more exciting & actually drink it that way. Juice they are allowed once or twice a day.

But DD2 only wants milk. As soon as she finishes a drink she'll ask for more. She still eats plenty & is a pretty good eater, but she has milk at least every hour or 2.
She won't go to sleep with out a pop top, or cup with lid with milk in it.
I try not to give her much. 100 - 150 mls usually at a time, but I'm worried she's having waaay too much.

She might have one or 2 drinks of water a day. Usually its a full small bottle, around 300mls. Sometimes will have it out of the tap with a straw.

Is that too much milk? Would you be worried? Do you think its ok??
