My 8 day old baby pees only once a day and has not pooped for 3 days. I m giving her only breast milk for the last 4 days. Before that it was a mixture of formula and little breast milk as my supply was less.. ever since she is one only breast milk she has not pooped. I m in Hyderabad. Can weather and dehydration can be a reason? Can I give her some water. I feed her every 2-3 hours for 20-30 mins.
