When LO was 4 months she began to roll over in her sleep. We had a rough couple of weeks and then it seemed to pass- she stayed on her back. She is now 6 months and the other night she managed to roll over in her sleep sack. So we have been putting her to bed without it- might as well make it easier for her. It's obvious she wants to sleep on her belly and we are ok with that. The problem is she doesn't seem to know how. She will sleep for a bit and then wake up a bit, lift her head, army crawl around the crib. The other night she face planted into the mattress. She has also been getting her arms and legs stuck in the slats of the crib so the mesh bumpers went up this morning. Will she eventually get the hang of sleeping on her belly? We were going to start sleep training on Saturday but now with this going on I don't know if we should postpone it? Anyone else deal with this?
