Sleep confused

Bailey

So my baby is confusing me. I think he’s going through a weird sleep regression/teething. He’s a week until he’s 6 months. He’s sleeping like 9 hours at night then I feed then he will go back to sleep. However he used to be able to generally put himself to sleep atleast for naps but now if I try to do that he just screams and screams only sleeping if I feed him to sleep. A part of me wants him to be able to go to bed on her own but If he’s sleeping that long should I just keep doing it? Why fix it if it isn’t broken ? I know I’m lucky he’s not waking every hour so I’m sorry if you are. He’s chewing everything, fussy, won’t let me put him down in the evening and acts so relieved when he chews my finger.
