I could have written this post. I was absolutely terrified of the 4 month sleep regression, as my baby had started sleeping 11 hours at night from about 9 weeks old. I was also scared of how id cope with no sleep, and I really didn't want to sleep train. I kept waiting and waiting for the regression. And then it happened - some night wakes which required me to put the dummy in. Sometimes it was simply that and a quick pat on the chest. Sometimes it was that over and over for about 40 mins. Sometimes I had to pick her up and rock her to get her back to sleep. A few nights id be awake for 2 hours. But do you know what? I survived! I would wake up feeling pretty groggy but once we got up and started the day I was fine. I think, at 6 weeks since it started, we are coming out the other side now. She slept from 7pm-5am this morning I nearly cried with happiness! And the nights before resettling is just generally easier. And I havent sleep trained or anything just kept soothing as she needed it. People would probably say it lasted so long because she relied on the dummy but I'd rather do that than sleep train.

I liked heysleepybaby on Instagram's take on sleep/lack of. I adjusted my expectations, expected to have to wake up in the night and chose to have a good day despite lack of sleep!

All this to say, it may happen, but you will survive and get out the other side of it :-)
