Baby is 18 days but she does not poo and stomach have a lot of wind and baby keeps crying. What should i do?

If your baby is exclusively breastfed, then it is not unusual for her not to poop everyday. This is because breast milk has the perfect nutritional balance for your baby and therefore there's very little waste produced from it. Also if your baby is going through a growth spurt, she could be absorbing pretty much all the breast milk, leaving even less waste than before. You should worry if your baby shows signs of discomfort, seems fussy, or starts feeding less. Also when your daughter does pass stool to check the diaper to see if the stool is hard or bloody. If she shows any of these signs, and/or has not pooped for a week, then you need to see the doctor.
