i have a nice 1 tog grobag for 4-month-old DS (made of towelling with a cotton liner - no padding) which i'd like to start using.
the bedroom room is 17 or 18 degrees and up till now he's had a sheet and two blankets and seems warm enough and not too hot in bed.
so i think he'd need the grobag plus a blanket - but various sites on the web say don't use a grobag with a blanket. why not? if it is well tucked in at the sides of the mattress and he can't snuggle under it / pull it up over his face, can't i use the grobag with 1 blanket on top?
i know i could get a warmer grobag, but they're expensive...
NB i've tried grobag's site but not much enlightened.
