i would make a list of each child's weight in kg, and work out their rise.
THe rise is:
get a tape measure, start at their belly button, take tape down under their bottom and up the back, to the small of the back. That length is the rise. It really helps to know the rise to accurately buy a good size for your child - when you buy online and can't try them on first, every assistance (e.g measurements) will help.
THings i see mentioned to help heavy wetters are things like:
- super thirsty bamboo trifolds to boost, or insert in night pockets
- 12 and 16 ply wool used for longies (if using over a fitted night nappy)
Nappies that don't need covers (they come with waterproofing outers) are styles like
- AIO (all in one)
- Ai2 ( all in two)
- pockets
the difference between them?
AIO - one thing to put on baby - waterproof outer, absorbency is sewn into the nappy, inner of nappy is a stay dry fabric usually
AI2 - one thing to put on baby - waterproof outer, absorbency is made up of boosters and trifolds that are often snapped into the inner layer, stay dry layer lines the nappy
POcket - one thing to put on baby - waterproof outer, absorbency comes from the insert or trifold that you stuff inside the pocket opening, stay dry layer lines the nappy.
So either of those three will mean NO COVER.
THe beauty of the fitted nappy is that sometimes, it's easier to boost them, esp for a heavy wetter.
i'll try to think of a few examples of each style for you,so you might go browse, to help you research

Nurture nappies has this thirsty booster called a Super Bambooster, i lie this inside a malden mills cover and it functions like an AI2.
Most nappies go up to 16kg no worries, i don't know the weight of your 4yo obv, but if he's over 16kg, the KK AIO by request is what would come into my mind first, just email the PP site.
