My dd is almost 5 weeks old. After a day of being fussy yesterday, refusing to fall asleep and when she napped it was only for a few minutes, I managed to get her to sleep at about 1:30am by swaddling her (very thin cotton swaddle in the heat). She then slept until 7:30am and I had to wake her up to feed. I usually wake her if she goes to 4 hours but I was soo tired I didn't wake up. I'm not sure if its OK? I kind of feel guilty about her going so long without food. She's ff, born 8lb 5 and now above 10lb.
