My sweet baby went from being an excellent sleeper, putting herself to sleep and sleeping 10 hours a night, to a hot sleeping mess!! A month ago she went through a second sleep regression which led right into her cutting two teeth. Now the teeth are in, the regression is over but she’s still waking up 4x or more a night!! It’s like everything we did to get her to sleep earlier has been wiped out. My husband and I are a wreck and we don’t know what to do. Please help or share anything that worked for you. Baby sleeps in crib, we have the same night time routine since birth, use a sound machine, black out curtains, sleep sack or weighted onesie. 😩😩😩😩😴😴😴😴
