FTM advice needed on bedding/carrycot/crib

[Pastaalldaylong]

We have got a pram which has a carrycot which we aim to use out and about and also in the house for naps.
Do you use a sheet over the top of the carrycot mattress? A waterproof sheet? Blanket and sheet underneath baby for a bit more comfort?

I also will have a Snuzpod crib for nights which I have bought waterproof sheets for. Should I use the waterproof sheet, with a normal sheet? Do I layer sheets to easily whip off in the night in case of leakages etc.. and again - a blanket underneath for comfort? Or not needed?

Thanks!

I’m using a mattress protector and fitted sheets, then grosnug, same in carrycot and crib. I will layer crib sheets with a muslin under baby’s head to limit changes.

No to blankets underneath.
