I introduced water with solids at around 5 &1/2 months dd1 went on solids at 4mths due to reflux & was constantly constipated from then on so the water was to combat that. But only at meal times. She had nothing else till 13mths when i introduced diluted juice. She still doesnt have anything other than water, milk or diluted juice shes 3 in oct. I think its normal. I wont be giving dd2 water or anything till after solids have commenced.
