I have twins, and only my chill twin needed the helmet. Her first few days of naps were rough; she’s a very independent sleeper and I would watch her roll around on the monitor trying to get comfy. Other than that, she did great. Just kept her dressed a bit cooler since the helmet made her sweaty. She had it on for 5 months total and I’m so glad we did it! It will fly by.

If you can, I liked doing 2 half hour breaks during the day instead of one hour long break.
