Hi guys, my little one has started to wriggle in the night so I don't feel right leaving him with a blanket tucked in in case it goes over his head in the night, changed him to a grobag but he likes to spread his legs wide when he's asleep n ends up waking cos the grobag isn't wide enough, they all seem the same sizein 0-6 n the 6-12 r too big that he'd slip down, I'm just wondering if a think baby grow would be enough or not? Obviously don't want him to be cold, its usually 20-21 degrees but drops in the night so not sure what to put him in?
