No bowel movements in last4 days after shifting to formula for my daughter, 23 days old. Urination is normal. Please advise?

Don't panic. Could be the type of formula - sometimes cow's milk formulas can be constipating. Check with your doctor to see if a switch is advised.
Call pediatricia now. Your pediatrician knows this newborn best. Call him/her now. You want to get ahead of any complications early.
