Is my cat changing?

Hi everyone,

My cat <1 years old was used to snuggle in by my chest every morning for an hour or so

It was the best thing in the world.

She has stopped doing it for some reason… she would still come up and check in but turn around right away. It’s been a week or 3 now I think she did it for the last time

She still comes up my lap during the day and follows me everywhere

Is she changing into a less cuddly cat? I actually thought cats would become more cuddly as they get older?
