Still trying to get Delilah to sleep better at night, she goes down awake with a full tummy and falls asleep fine, she’ll sleep a couple hours and then is up and down anywhere from every few mins to couple hours after the first couple hours of going down until like 5 am then she’ll sleep another couple hour stretch. I’m at a loss I swear I’ve tried everything I have found online. We’ve done her naps earlier, putting her down a little earlier around 10 (she was going down at midnight that’s when she would be ready to lay down) tried a night light, tried dark, tried a movie on her tv, tried without, tried letting her cry which does NOT work she will literally cry for hours, tried feeding more, checking her diaper, teething tablets as she’s now cutting 2 more teeth but this has been ongoing for months so think that’s unrelated, baths in evening, lavender soap and lotion, making sure she’s not too warm or cold, etc I could go on but I think y’all get the point lol. Anyway just looking for more advice as I said it’s been months that she’s been waking constantly and screaming through out the night. I am exhausted. Hubs offered to stay up and keep an eye on her last night which was amazing but I still heard her every time she woke and it was ALOT like 2 hours after she went down she was up probably 7 -8 times over the next few hours. Seriously need help! I can’t live my life on an hour maybe 3 on a good night of sleep. We’re beyond exhausted! Sorry for long post just wanted to be thorough. Thanks ladies!
