We have used these nappies since birth. They are good quality and very soft, however as our baby has grown and become a little more wriggly, we've noticed that they are quite short up the back (and our little girl is only 10th percentile, so not a big baby!) Every night where she moves around in her bassinet, the nappy seems to slip down a little at the back and we end up with a wet sleepsuit and sleeping bag. We have secured very firmly to try to prevent this, but it still happens. It seems the nappy is too small despite her only being 4kg (recommended up to 5kg). It's a bit of an annoying situation as the next size up is massive (4-8kg) and comes up to her armpits almost, and they're also ginormous on the legs! When we do move up sizes, there is the inevitability that they are then going to leak from the legs (as this size did initially when she was smaller).
It seems that with Huggies nappies, we can either have leaking from around the legs, or leaking from the up the back. We will be testing other nappies in the market to see if we have any luck as have had similar feedback from our friends re: Huggies too! Such a shame as this bulk supply offers good value!
