Advice needed!

1) My brother sister duo (4 months old) sleep on my face and removing them again and again doesn’t help, I have two cat beds on my bed. Dad says they are just breath stealers, I don’t mind but I am a chaotic sleeper prone to sleep talking, walking, ever lashing out at my walls and don’t wanna hurt them.

2) they never meow, when they wanna wake me up they just sort of pur really loudly and knead my face- does this just mean they want attention or they want breakfast etc

3) they climb up me constantly, onto my lap when I’m peeing, onto my shoulder when I’m cooking or cleaning the litter boxes- it’s cute and I’ve learned to wear layers because I (still kind of am) covered in slices- I don’t think it’s possible to give them more attention!

Are these all just normal kitten things or am I not doing something they need?

The slow blink at me and push their foreheads on me to get me to give em kisses so I’m sure they are happy, maybe I’m raising clingy babies?
