Toddler DS has up until last week been sleeping in grobags in his cot bed (side still on as he's never tried to climb out so haven't changed it.) As it's been hot we've been covering him with just a thin blanket and he's still slept well, although he does kick it off. We're therefore going to ditch the sleeping bags and move to bedding. I was going to buy a duvet set but then wondered if it would be better to just buy more blankets. He currently still sleeps in a nappy but at some point won't and I wondered if it's easier to have multiple blankets for when he wets the bed for washing, drying and having spares than trying to launder a duvet. What does everyone else do?
