Hello all! My 11 week old has gone from sleeping 2hr stints (night and day naps) to waking every 45mins. He will sleep longer for contact naps- it’s leaving me with a very grumpy baby! We have tried putting down drowsy but awake but this just wakes him up. Could this be the 4month sleep regression come early? He drifts straight back off when picked up! Any advice welcomed thanks!
