Toddler sleep attire

[AlmostAlwyn]

My 20-month old has lately started waking up quite frequently in the night and I'm wondering if he might be cold? We bedshare, but he doesn't have any covers over him. He wears a short-sleeved vest and a footed babygro. Is this too little? I've been looking at sleep sacks (footed ones from Slumbersac). Does anyone have experience with these? Do they make such a difference?

We don’t bedshare, but my DS had a sleep sack until he moved to a bed at around 22months and DD uses them now at 15m. We never had the ones with the feet holes as they were in a cot.

At 20 months he could use a blanket though. Can’t you get a toddler duvet for him? They are just smaller cot bed size duvets and are lighter weight
