My 13 month old DD is weaned onto food now except for one bottle at bedtime. I tend to have fluid on offer for her most of the time but recently she seems to be drinking just for the sake of it rather than actual need, as she has drank so much a couple of times that she has actually made herself sick and obviously I want to avoid this. We use the tommee tippee cup that holds 200ml and she gets a cup of fruit juice at meals so 3 times a day and also watered down juice in between meals so one cup each in the mid morning and mid afternoon, does this sound like enough?
