Ds1 is 2, just. His first two winters he wore grobags but won't be this year. He's very tall, and was starting to wake up having got tangled up.
In the absence of the grobags how on earth do you keep them warm at night in winter? The nights are cooler now and he's wearing a vest and warm pj's with socks. But this won't be enough in winter, and he's such a wriggly sleeper he'll never stay under a quilt. He often ends up facing the wrong way, or across the cot.
