Think about how many attachments this little boy has already had and lost. He has no idea who is going to be there for him each day.
Talk to a pediatrician, speak with a therapist who is knowledgable about attachment issues.

Will he let you wear him in a sling or carrier? That would help build attachments.

He may bond with you but may never be affectionate for a few reasons. His history or that may just be his temperament. Or he could become really affectionate after he learns how to trust. Can you live with and love a child who isn't cuddly?
Or, even more importantly, may have attachment issues?

At 9 months old, most babies are holding their own bottles and starting to feed themselves.

Talk to some folks and give it some time.

Good luck.
