So, my LO is about 10 weeks old. A few weeks ago he started consistently giving me a good 4-6 hour stretch when he first went down at the beginning of the night. And he also would go down fairly easily in his RnP. About 5 days ago everything changed. He has been so hard to get down. Taking up to 1-2hours and his first stretch now is more like 2-4 hours. After that I give him a paci and he sleeps off an on for another hour (replace paci a couple times during this time). He's not really eating more during the night but is up more and way harder to put down. Anyway, where did my sleepy baby go? Did anyone go through a sleep regression like this and did it go back to normal? Any advice?
