Huggies here too. DD is now 3 and only recently begun TT, and they're still holding everything in overnight.

Even when she was in plaster - she was in a spica cast and we had to cut the sides and tabs off a newborn nappy, making it sort of like a pad. That slid into a slot in the spica, and then a bigger nappy went around the cast holding it all in - even with that set up, we had very few leaks into the plaster, the Huggies absorbed most of it.
