What is 4mo Sleep Regression?

Question

I am curious about the 4 month sleep regression. I’ve read about it and I know it sucks but I am more specifically wanting to know when did it start for your LO and what are they doing? I’m trying to figure out if we are in it or not?? Some nights are easier than others. Wonder weeks says we are in a growth spurt and have 22 days left 😳 my LO has been extra sleepy during the day, feeds more and restless at night but not fussy.

Answer

Someone correct my response if I’m wrong.
As newborns they cycle between 2 stages of sleep and around the 4 month mark they start to cycle between all 4 stages of sleep, which includes more light sleep where they’re easily woken. Then, because they’re easily woken, if they cannot self settle they’ll wake up and need help being put back to sleep.
This is our issue, she likes a dummy to “go” to sleep, for the first part of the night when she deep sleeps she spits it out pretty much right away and used to sleep through. Now, anything after midnight is fair game and she will cry until we put the dummy back in, but she spits it out when she drifts off but because she is only in light sleep it wakes her back up.
The increased wakings started around the 5th of Feb for us (she woke frequently also on the weekend I didn’t log) xx
