They get themselves really dirty when learning to eat, and they are still too young to be litter trained so they cover themselves with their pee and poo too! We have been using small animal shampoo (mild enough for kittens) to shower them at least once every two days.
When they get the bottle, they now can drink half a bottle each, and I add vitamins and probiotics for them in their milk too, so they can stay healthy. Handreared kittens might tend to be a bit weaker in immunity and such because they miss out on their mother's milk, so the supplements are necessary to ensure they are healthy.
I handmade a reheatable pillow - using a towel with barley grains inside, when microwaved stay warm for long - to keep them warm. Right now most of their pillows are already soiled, they have one for now in a small basket which they cuddle up within to keep warm.
