My 5 month old baby no longer sleeps very well at night. At around 10 weeks he was going 10-11 hours but now is awake for hours a night and up 3/4 times, this has been happening for almost 2 months. I obviously know about the sleep regression but everywhere I look it says this typically lasts 2-6 weeks. In the daytime he sometimes has a long sleep for 2/3 hours at lunchtime. Should I be stopping this and waking him up after an hour? He clearly needs the sleep but would rather him be getting that at night!
