Hours spent breastfeeding

Hey everyone,

I was just wondering how many hours per day do you spend breastfeeding(ebf)? I started from 8 hours and now at 11 weeks it is somewhere around 4 hours total. However I'm starting to worry that it is too little time for my baby to feed properly, since he started again a hectic program of napping for half an hour then waking up crying, then failing asleep again while breastfeeding.

Update: thank you all for your comments. This made my worries go away.
