Pavlik Harness and Sleep

It’s been two nights and baby wakes up every hour. He was using the love to dream swaddles before the harness so I just sized up to have room for it. I don’t know if it’s gas related because of the harness that’s causing discomfort, the swaddle and harness getting too hot for him…idk but his sleep has been impacted and I need help!

What worked for y’all?
