Sleep help. I’m lost..

I need some help mommas.. my daughter will be 7 months next week and she is by far not the best sleeper. We get about 3-4 hours at a time on good nights and she likes to be fed a couple times a night still. So the only thing that will allow me to put her down is her being in her Merlin’s magic sleep suit (pictured below for those who aren’t familiar.) But it says on the instructions that once baby is able to roll to side and tummy to discontinue use. What the heck do I do now? I’ve tried a wearable blanket and I’ve tried her in just jammies and it does not work. She screams, fusses, rolls around and pulls up on the side of her bed. I do not know where to begin to help her adjust to this change. Any ideas and help is so appreciated. Thanks moms!
