Sleep regression?

Kelsey

Any one else’s 16 month old going through a sleep regression right now? Mine will go to bed so easy at his bed time which is 8pm. And the. Around 11-12am hes up screaming/crying. We’ve done the cry out method and it doesn’t seem to be working with this regression..anyone else or am I the Lone Ranger?

Ps he’s been sleeping through the night for a very long time. So this is new territory for us😬😴
