If you use a sleeping bag you shouldn't need blankets so bub lies in the middle of the cot. It's only important to put bub at bottom of cot if you have blankets because you don't want them to wriggle under them.
Oh of course lol

She doesn't seem to like bein wrapped, she likes her arms up above her head lol. That's why I like that this one has sleeves, her arms won't get cold being out of the blankets. I'm not too stressed about her overheating, we have a temperature control heater in our room, and the sleeping bag would be lighter than the blankets she has now. Certainly wouldn't use one with a hood though - we've had it drilled into us she needs her head uncovered at night to prevent overheating.

But yeah, it may be good for the pram - the temp struggles to get into double digits here in the valley!

Thanks heaps everyone
