Is this the 4 month sleep regression?
I am wondering if my 13 week old is going through the 4 month sleep regression. I see various explanations online for her sleep changes and am not sure - like developmental leap, growth spurt, or regression.
In the past week and a half she has gone from sleeping a 4-6 stretch, eating, sleeping another 3 - 4 hour stretch to sleeping about 3 hours, and then waking up every 1,5 hours for the rest of the night. She wants to eat / confort nurse in between those (which she never did before). She has had maybe 2 better nights since this started but that’s it.
What do you think it is?
