I breastfeed my daughter. Well she seems like she is always sleeping. She is 1.5 months old. She is usually only awake long enough to cry to get fed and maybe awake for a diaper change. My son was on formula at this age and he seemed to be awake more than asleep. Is this normal? She is getting up about every 3 hours for feeds and is awake for maybe 5 minutes each time.
