Go with whatever feels most comfortable.
With dd1 I took sposies as I d never changed a nappy either.
With dd2 I took sposies and muslin squares already folded and wraps with me. They put a hospital nappy on her first and then I used my cloth.
I only stayed in 1 night with both and they were born in the evening so wasn t there for long.
This time round I think I ll take a mixture again.
Top tip would be to have a bag of baby clothes and whatever nappies you re using that are likely to fit, somewhere where DH / partner knows where it is
