Bad idea for children? I often have a hot water bottle in bed if it's cold, ds2 cones in bed with me forvthe second half of the night. But ds1 (3) is in bed on his own, not great at keeping his cover on (I check at 11pm and again around 3 or 4am)
I'm a bit concerned that if it's a colder winter this year, I'll struggle to keep him warm. Oil ch and just me, can't afford to have it on all night.
Thinking a microwaved wheatbag might help? But he's only 3 so not sure if they are suitable.
