what do you do about the gap between the shirt and trousers? We don't use sleeping bags and I don't think Lili would like being stuffed into one now, she's a bit of a wriggler. I'm liking our longies at night, but she inevitably kicks off her blanket at some point in the night and her shirt rides up and she winds up with a freezing strip across her back (it's pretty cold in our room!). She always wakes up at least once in the night (sometimes several times), and I while it's certainly not the only factor I think at least sometimes it's because she's gotten so cold.
I can't tuck a long shirt into her woolies
, but can't think of anything else I could do either, except maybe put her in a super-huge (ie long) shirt with the sleeves rolled up?
