Try a lil bit like 1onz of prum juice... it happened to my son when he was about that time and that helped him ,hes 2yrs now ,nothing happened to him
Do not give baby water in between! It's a Def no no!! My son was the same way when he was about 3 wks Dr had me put a tiny pinch of brown sugar in w his milk to get him going but I also had to do a suppository to get the hard poop out .. baby at that point should still be pooping daily and a cpl times a day 5 days is a long time for baby not to poop I would call scabies peds and see what they recommend not every Dr recommends the same thing but that long can't be good on babies belly
She should not b drinking water it's to early but I'd call the Dr
Does she seem uncomfortable? Is she still eating normal amounts? And water is a no no. Call her pediatrician if she is umcomfy not eating and not having a normal amount of wet diapers.
