noooooo don't do that mix it with the formula! a quarter ounce I give my baby it 3 x a day makes her poop

@mommytobe03.31, yes it's fine. Any baby section sells the juice. Target, walmart, publix etc.. Yes mix it together

a couple of times when that didn't do the job I took to the baby medicine section and they had an all natural prune concentrate that you mix with their milk I can't remember what it was called but that worked!

Even if she's only 1 month it's ok ??

yes what @marce88 said! you can go to your local grocery store and in the baby food section they have Gerber baby juice. or you can use any 100% fruit juice. b

Where can I find the baby juice (prune )

I mix it together ???

Baby juice diluted with water. Apple, pear or prune. 1 oz water 1 oz juice.
