My baby of 8 weeks hasn't had her stool in 2 days is this normal or should i be worried?

Normal: This is common. As long as she is eating fine, not vomiting, no fever, not to worry. If it continues, the baby should have a weight check to make sure she is taking enough calories, since insufficient calories can cause a decrease in stools. Assuming that you are nursing, sometimes dairy in your diet can also cause constipation. If it continues and her weight is fine, consider stopping dairy.

That depends upon: If your baby is behaving normally, has had a fever, or other recent illness. How is your baby's appetite? If everything is otherwise normal, probably she needs a little more fluid. Summer is a difficult time for little ones that become dehydrated easily. If she appears to be in pain or if she has a fever or vomiting, if she isn't making urine normally, have her checked out right away.

If she is: Breast fed it is 100% normal. Is she is bottle fed it is normal if. She is eating and acting normally. If she starts to grunt and push then call your pediatrician
