With DS I found that Snugglers were absolute crap, and so were baby love. However, if Babylove are on special and I'm in desperate need, I will buy them and then complain about them. Nothing in particular about them, they didn't leak or anything, but just crap.
I buy the "You'll love coles" ones - the blue packet which are fantastic! Love them. And I use a Huggies nappy at night because I have found them much more absorbent. He used to leak out the top of the huggies as well, until I got a tip from my SIL to fold the top over to make it more snug against his tummy. Since then, no more leaks!!!
Good luck!!!! I did a bit of trial and error before I made the final decision on these ones
