Dare i say they are better overnight?! We switched to disposables overnight, because they were much less bulky, didn't stink, and held as much if not more wee. I've used to the Aldi ones and Huggies in the past. I didn't really notice a difference..... But i have heard people swear huggies are more absorbent than any others on the market.

For super heavy wetters, i've heard of people either buying the next size up, or putting two on! The packets have weights on them, so just buy the right weight range for him. If he's on the cusp, go bigger.
