We have a 7-month old baby and we have been using Enfamil Gentlease for the longest time. Because of the formula shortage crisis, we have no choice but to use Nestle Good Start because it's the ones we got for free before and we just kept it for emergency. It took several hours for the baby to adjust to the taste. The bigger issue is that she struggled to poop. She had an agonising solid poop experience. Is this normal? Has anyone ever tried experienced this with their babies?
