my baby latches for 6/7 minutes only. only one breast at a time. she falls asleep while nursing. her birth weight was 2.6 KGS. now she is 4.1 kg. is that okay?

A. At the initial stages ( for the first few minutes) the breast milk is watery, after few minutes only the improved quality will come from mothers breast which will give more immunity power. New born baby sleeps per day on average of 15 hours.
