Hmmm, I use huggies at night but I haven't had to buy the new ones yet. The only time Charli wet through at night was when she needed to go up a size.
I have heard rave reviews about Aldi nappies and I have used them a few times (except the newborn size as they are a real funny shape - well the ones I bought were anyway) but all the other sizes are great. The Coles brand are also very good too.
