LO is nursing longer and longer, but is still hungry after. Not just a little bit hungry, either: she cries with exactly the same intensity as before her feed, then guzzles down around 1-2oz formula. She was a big girl to begin with (9lbs 9oz at birth, 10lbs 4oz at her last weigh-in) and I know that she's only getting bigger, but it just doesn't feel right that she would still be so hungry after nursing for 45 minutes, or even an hour?
Re: Does this mean my supply is low?
That was my first thought, but this has been going on for a week or so now. Can they last that long? I don't actually breastfeed her much at all any more, although I am pumping. It seems like every time I breastfeed her it now takes forever and she's still hungry afterwards.
There's basically a 3-4 day growth spurt at 2/3 weeks, 4/5 weeks, 6/7 weeks etc... so yes, it can last "that long." If she's not on the breast I'm not sure how to suggest pumping through a growth spurt but in general the frequency of nursing is what queues the body to meet the growing demand.
