When a baby (under 12 months old) is constipated, you can add 1 tablespoon of dark brown sugar to a bottle of breast milk, formula, or water. Shake well and feed the baby as you normally would. You should see results within 12 hours, or, if you don't, it's safe to repeat as many times as necessary. My pediatritian told me about this trick and it works wonders in our house. It's totally safe, non addictive, and gentle on baby's delicate tummy! Good luck!
