My 10 month old clears 3 7oz bottles of formula a day, but refuses water. In the hot weather, I have been offering water regularly and am worried he will become dehydrated with only milk. I tried him with some juice which he drank straight away. Can anyone advise which juices are safe to give to babies without rotting their teeth. I know that juice should be given by cup and should be given at meal times and for short periods of time. Should I give specialist baby juice, sugar free juice, Hi juice (all diluted vey thinly of course)....I'm so confused! Please help.
