my daughter is 8 weeks old and is constipated , what can I give her to help her poop??

2oz warm water and a teaspoon of brown sugar every few hours if it doesn't work the first Bottle

Gerber's baby prune juice mixed with water

call her doctor and ask! they might have some easier alternatives to try. before trying anything with constipation is it better to ask her doctor babies can get blockages and impactions and those need medical attention. and giving her something she isn't ready for can hurt her belly even more.

try bicycling her legs and massaging her stomach. I use also bring my daughters legs up to her ears a few times.
