If you disagree with sleep training I respect that, but please don’t judge!

My LO is currently in a Merlin suit, but the weather is getting warm and we’d like her out of it in a regular sleep sack. I’ve tried, and she immediately rolls to her stomach and loses it! Almost like she’s forgotten she can roll back (and she is able to).

We were hoping to start sleep training next week, and I know a lot of people have said to let her figure out how to roll back. My question is do we do both at once? The heat is really driving this, we do have a/c units but I’m wondering if it makes sense to do it all at once? Or sleep train first and then transition out?

Any experience with this or tips?
