My 3 month old previously has been feeding for up to 30mins on each side, 5 or 6 times during the day and sleeping through 11pm-7am. In the past week she has become very fussy and is now only taking 10 mins before pulling off crying and refusing to go back on the same breast, but will take another 10 mins from the other side. After that she refuses to take any more, crying and turning away. I am worried about her getting enough food and also worried about developing mastitis again if my breasts are not fully emptied. Any ideas, experience or tips would be gratefully received!
