Dear 4 month sleep regression 🖕🏻

Samantha • Emma 👧 💕 Nov 2018 👶🏻 Stella October 2020

Anyone else?? It hit my girl like a ton of bricks the other day and holy 💩 it’s killing me slowly. We sleep trained before thinking it would help and it clearly didn’t do anything so yay to restarting. Any tips of how to get through this smoothly would be much appreciated!!
