Newborn has had diarrhea for 5 days

Melissa

I am wondering if I should be concerned for my baby or if something serious could be going on?

I called my doctor’s nurse and she and my doctor spoke and said it is possibly a lactose intolerance and for me to cut out dairy my and monitor did 2-3 weeks.

If it’s not dairy, could it be something more serious? Has anyone experienced diarrhea in newborn before?
