what do you dress your toddler in at night in this freezing weather?

[silvermum]

DS 18 months has lived in GroBags since he was tiny, but I haven't been able to find any really warm ones with sleeves...anyone got any tips?
we've never tried pyjamas + blankets because he wriggles around in his cot so much he'd end up throwing the blankets off within half an hour....
we did find a fab thing from jojomamanbebe but it's been worn so much during this cold snap the zip has broken. (i will try to fix it!) Am about to buy another but they're expensive and he can only just fit the largest size so i'm a bit unconvinced.
Anyone found any good solutions?

DS sleeps in a vest with a fleecy baby gro over under a duvet. If he gets cold he just pulls the duvet back on himself. His room is very cold and he is fine.

vest, PJ's, socks, duvet.

Nope she just went to sleep, however DH and I were brave and before we went to be put her PJs back on whilst she was asleep - luckily she didn't wake up, in fact we got a lie in to 8am!
