YUP it doesn't like you and it is not comfortable with you
When the mother rejects a kitten is often because there is something wrong with the kitten. It's natures way. However, if you take the kitten to the vet it's very possible you could pull this kitten through whatever is wrong, but you will have to be available often during the day and night to feed the kitten and to be sure it has it's medications.
It is a normal habit but when it grows bigger it will stop
It might have something wrong with the muscle or bone. Next vet visit get it x-rayed.
You should see your vet or pet shop to get the proper medication. A six week old kitten is too small to get adult cat medicine and you can hurt it with the wrong stuff.
I have a 5 week old kitten that my fiancée and I rescued and he's healthy at 1.3lbs
there are spacial kitten foods.
yes
A 4 week old kitten's eyes are not supposed not to be small since they open up by the second week hence they are becoming big.
I've heard it is usually once a week. Unless the kitten got into something dirty, it doesn't need a bath. Kittens/cats clean themselves.
Not usally and if does twice in a week something is wrong.
Like about a week later when you asked them anything or they said something
if your kitten is bleeding from his "bum" he is sick and should go to a vet
