This is probably a really stupid question and probably has a really obvious answer but am completely sleep deprived. DS who is 7 MO has been really good at sleeping, except he still needed his 4am feed which we've eliminated in recent weeks. Now though, he's discovered rolling around the cot, often from 2am thru to 5/5.30 getting stuck with face in bars, wedged into corners etc. He's in a grobag. I've tried everything bar sewing him to the mattress Heyulp. We now wish we'd never got rid of the 4am feed getting up once in the night with guaranteed result was simple compared to this.....
