My daughter is 4months old. Her birth weight was 2.5kgs and now she is 4.7kgs..Although she sleeps well and night but during the days she barely sleeps for 2hrs..She is exclusively breastfed.. She passes urine atleast 15times in 24 hrs.. She poops regularly except 3days since her birth.. My question is why does she sleeps so less?? Can the factor be hunger??
