*just going to get this right out of the way-we used the snuggle me pillow “inappropriately” in the crib*

Our son is monitored with video/audio/and an owlet heart and respiratory monitoring sock. Because he was so monitored, I reluctantly let him sleep in his crib in the snuggle me pillow because he physically could not roll out of it. However, I’ve seen him trying to get out of it lately so it’s time to remove it. He is absolutely FREAKING OUT with his newfound “freedom” in the crib. He rolls around and bumps his head on the slats. He used to sleep 12 hours straight and if he woke up he would just play with his feet or fidget then go back to sleep. Now he wakes and does 360’s and flails around and becomes hysterical. We’re on night 3 of him sleeping in 30min increments at most. I know I can’t be the only one to experience this, any advice is so appreciated, he’s miserable and it’s so upsetting.
