I gave my daughter half a glycerin suppository she is 7 months old i haven't seen much poop yet should i give her another half ?

Once a day: Don't give glycerin more than daily for constipation, but if your 7 mo old is constipated, you need to go to the doctor and find out what the problem is, maybe adjust the diet a bit. Go talk to your pediatrician, will do some good !!

Constipation: the first question is weather your infant has constipation considering the frequency of bowel movements vary from 6-7 per day to one every 6-7 days. But it's true that your baby is constipated,giving another dose 12 hrs later should be OK
