She is constantly fussing and rooting when shes put down or someone else holds her, but only feeds for a couple of minutes and sometimes only just a few sucks when I have her back, then settles and looks asleep but wakes up again when shes put down. Does it sound like shes hungry and finding it too much effort to get enough or is she old enough to be clingy?
My 6 week old does the same. He uses me as a comfort and enjoys suckling. I've let him as it's really increased my supply but he will snooze 5 mins into a feed then wake shortly after for more. The initial few minutes of a feed the milk is very watery and quenches their thirst and gradually gets creamier and increases in calories which Satisfies their hunger. As long as bubba is gaining weight and you are getting enough wet and soiled nappies a day I wouldn't worry
