It is very coming question about the kitten coat.
And it is not easy to answer this question, when kitten in age of 3-4 month old....
Many different combinations of Peterbald coat mite be seen on kittens from same parents.
Here is some basic examples:

It is not easy to predict some times final appearance of Peterbald Coat.
Some kittens may grow additional hair, and coat become more heavy.
Some will loose coat and become almost bald.
Some will grow coat and then loose it completely.....
Most of my kittens will grow some coat after 4month and then gradually loose
it, become Thin Flock.
Those two kittens was identical up to 4 month, then Chocolate tabby girl become Brush,
but Lynx point boy become Flock-Velour.

Bald mother can give a birth to all kind of type of coat.
Same litter may include bald, brush, flock and strait coated Peterbald kittens!

 

 BALD
Sticky bald kitten will need additional care for his eyes, ears and body. Because it does not have
any protection. Just like new born baby.
Gentle shampoo could be used for bathing. I will recommend to bath kitten at least ones a month.
Ears will need to be clean weekly. You can use any cream or ointment with low % of antibiotic.
Eyes may be cleaned with Therramycin ointment.

THIN FLOCK
Kitten born with thin flock may loose all markings. Brown tabby girl become completely
chocolate after 2 years old.
Those kittens need less care, but still very gentle bathing.
They may need additional heating pad ( I use regular electric $15)

THICK FLOCK-VELOUR
This type of coat may keep most markings. Color will stay.
Peterbald kitten will have curly whiskers and brows.

BRUSH (short)
Brush coated Peterbald is very unusual creature!
Funny fillings and some time funny looking body, but same gentle personality!
Beautiful Oriental appearance.
