4 month sleep regression - please tell me it ends
jolly-otter · 5/17/2026
Was sleeping 6 hour stretches. Now up every 90 mins. Day 9. I am a husk. When does this end and is there ANYTHING that helps?

Ours lasted 3 weeks. Then he slept better than before. It does end.
Make sure naps aren't too long during the day. We capped at 1.5hr after wake window of 2hr.
It's actually a permanent change in their sleep architecture - they now have adult sleep cycles. The regression is the transition. Once they learn to connect cycles, sleep improves.
Black out blinds and white noise made a meaningful difference for us.
Wake windows. 2-2.25hr for awake periods at this age.
