Giving a baby ‘prune juice’?????

Okay so I’m not a mother which is why I’ve turned to this poll. My aunt has just had her first born and it was a shock to her and I don’t think she realised how tough it’d be. My cousin has extremely bad colic when asked if she’s thought of changing her formula to one for colic babies and her boyfriend replied ‘oh it’s fine she can have prune juice in two months.’ The baby was one/two weeks old at the time.

He’s supposedly had four kids but honestly he seems to be blagging his way through acting like he knows everything, I don’t believe he’s actually looked after his own kids when they were born because of other things that have happened.

Now I’m very concerned about my cousin, I heard your not meant to give a baby water so why on earth would he think prune juice is okay?? What do you guys think?
