Our LO is 15 weeks old & has been a good sleeper since birth but the past few weeks she has woken up 4-5 times per night for no apparent reasons (shes well fed, burped, changed, swaddled, etc). We have been so exhausted lately that we decided to give sleep training a try. With her temperment, I really didnt expect it to work or go as well as it did! Needless to say we are only on day 2 & she is already able to put herself to sleep & last night slept 9 hours straight thru the night, then 3 hours more! We are ecstatic! & floored at how easy it has been. We keep waiting for something to go wrong lol. Fingers crossed that it stays this way for the full week of "training". everyone in our house is so much happier with a full night rest!😊
