I really love my W/C. I bought one new and got one on B4baby. Worth the money. It's last all night for us, no leaks ever. I only have 3, but when cash permits i would love another 2.

You can certainly put anything you like under or over the bubblebubs booster. Although i know i wouldn't get a very good legg seal on my DD. But worth a shot, you never know, might work a treat for you.

I know ittibitti have a night nappy in the pipeline being tested..... don't know much about it, but i presume it will be sized.

I also use a BBH boosted with a mazalicious trifold. This works really well also, but is very big on her bum! Which is fine as she sleeps on her tummy anyway, so i guess it doesn't bother her.

I use Maz minky covers, they don't have any PUL in them so are great overnight as they breathe.
