Is there such a thing? My 13 week old for over a week now has gone from sleeping 4 hour stretches to waking at least every few hours. I know there is a big leap and growth spurt at 12 weeks but this is still going on. We're exhausted. She goes straight back off to sleep but wakes again in less than 2 hours. Sometimes for a feed, sometimes for a cuddle. She is EBF. Thanks for any advice!
