S.H.
Bananas are binding.
A baby's digestive system is still maturing.
Hence, constipation.
Don't give bananas anymore. Until she is older.
Nurse, on-demand. For the 1st year of life, this is imperative. Breastmilk or Formula is a baby's PRIMARY source of nutrition, not solids and not other liquids. Solids, is also not as nutritionally dense, as breastmilk or Formula.
At this age, a baby does not even have to eat solids, 3 times a day.
Just once is fine.
Do not give anymore bananas until she is older.
Do not use suppositories. This is per our Ped.
