Do I still need to dilute Apple juice for a 6 and a half month old? If so, when can I stop?

I would, yes. I stopped diluting when Isaac turned 1.

Cayden's a year and a half and his doctor told me to still dilute his juice.

my nephew is 1 yr and a half and we still dilute his juice

I still dilute my 2yo dd juice most of the time lol Saves on juice and gets her some water too. Also helps decrease the sugar intake.

I stopped with all 3 of mine around 9 months. They refused to take it with water.

I only feed t 1 1/2 year old diluted juice! If you get the tots kind of juice at the store it's already diluted (: they have more than just apple juice too

At my daughters 9 month check up I asked what I could do for her being constipated and her dr told me to give her 4 oz of Apple juice daily and I asked to make sure. But asked should I mix it with water or no and he told me no. She is now 10 months and I just keep doing the straight Apple juice but I don't do it daily like he said, just if she hasn't pooped in awhile.
