When did you hit the 4 month sleep regression? If you did?!

I've had a few terrible weeks with Coralie's sleeping habits, week 14 was dreadful, 15 was OK but not great and then 16/17 was even worse Getting up 3-4 times a night, sometimes every 30-60 mins

Until Friday She has STTN the last 3 nights. I don't expect it to last since she's coming up for the 4 month sleep regression... or is she? I'm wondering if she somehow had it early? Is that even possible? She's only ever STTN a handful of times in the past, and that's always been 10pm til like 6am. This was 8pm til 8am Without waking at all in that period. I do dreamfeed her at 10pm though.

So if you lovely ladies could tell me when you went through it with your LO's i'd really appreciate it.

Should I be stocking up on the sleep ready for some horrendous sleepless nights LOL
