I've just got a grobag and been reading the SIDS foundations recommendation for how warmly to wrap your baby at night. The thermometer says 21 - and they reckon a vest and a high summer sleeping bag - a sheet basically. I'd be cold like that - and the babe (8wks old) feels like an icicle if I leave him for a few hours like that (a wakey grumpy icicle).
Obviously I want him to be safe... but does anyone actually manage to stick to these guidelines strictly?
