Is this regression or just a bad night?

[OnlyFoolsnMothers]

16month old usually sleeps 7pm-6/7am- last night Awake from 11.30-12.30 then woke at 1/2/5.30/6.45.... Ive read of 18month regression but appreciate it’s not an exact science.

I'd wait and see if it continues. One night isn't regression your LO might just have had a bad night

My daughters nearly 15 weeks and I keep thinking this every time she has a bad night as I’m super anxious about the 4 month regression! Although a few horrid nights are normally followed by a few good so I’m taking it as not!
