My 15 days old stay awake for almost 2.5- 3 hours sometimes when she wakes up. Earlier this was happening once during night time but now I am noticing it during day as well. She is exclusively breastfeefing. She is neither crying nor able to sleep. I checked using breast pump, I am able to express 40-50 ml milk in 25-30mins. Is there something wrong? I have read that children of this age do not stay awake for more than 1 hour.
