Ds used to sleep through from 11pm till 6/7am. Since 10 weeks this has stopped and he is now waking every 2 hours or so. Could this be the 4 month sleep regression early? He is now 13 weeks but is hitting developmental milestones early. He rolled front to back at 10 weeks and is now rolling back to front. How long is this likely to last and is there anything we can do to help. We've been trying to introduce a sleep schedule but he is terrible at napping during the day and I can't get him to nap for more than 15 mins unless he is in the sling. He used to self settle but won't do it anymore, he just screams so I have had to feed him to sleep. If we put. Him to bed at 7 he will only sleep 15/20 mins max. Then can't get him back down till at least 10. So frustrating!
