Really depends on the day, my 11 week olds average is 10 but she's done anywhere between 8 - 14 the last few weeks
My little boy is 10 weeks and since midnight has fed 18 times so far. Depends what mood he is in depends how long each session is but they vary from 3 to 15mins x
11 weeks and we're averaging 8-9 total feeds per day, with each one around 15mins.
