My 11 month old doesn't seem to want to self feed as much anymore?

I don't know for sure but perhaps the novelty of doing it herself has worn off? Mine is only 7 and a half months so I don't have experience with this but she was mad to be able to sit up and would try for ages, now she can do it, she isn't really bothered anymore! I would think it's only a phase, I wouldn't really worry.
