Constipation

She's 5 months old,she poops a little but it is so straining for her to do.I'm not sure what to do for her.

Have you tried applesauce?

Yes,and water,and a bath,and a massage,and bicycling the legs.

You could try a little bit of Gerber apple prune juice or apple prune baby food.

pedi told me to do 2 ounces of 100% prune juice twice a day, DS was a little over a month old when we started on that and then he started going good, his poop was becoming solid and he was screaming in pain everytime he wuld go and sometimes he would strain so hard he would bleed from his rectum.

Is he bottle feed? If so you need to be careful of the mix of formula and water. If you heap the formula spoon too much they don't get enough water and it can cause constipation.
