We just got Mally the Baby Dry diapers because she was waking up wet on some mornings, having peed through the regular diaper, her sleeper, and her sleep sack. The Baby Dry seem fine, but I'd never heard about using a one-size-too-big diaper at night.
I guess my big question is, wouldn't a too-big diaper be more likely to leak?
Re: s/o overnight diapers: tell me about using one size up
With my 1sy & 2nd boys, I always used a size up for at night time with no leaking problems.
I think because the baby is a bit smaller in weight than the other boys at this age that never worked with him. From around 4-7 months he always woke up wet in the middle of the night & I could not find any overnighters his size. I ended up putting him in 2 cheap diapers & that worked!

Sarah wears size 3 for the day (Luv's) and for the night (Huggies Overnite). Never had a leak.
