IMO 9 months is too young. But I do think it depends on the child. My first child couldn't go to sleep on her own till around 4 41/2yrs. My son will every now and then (he will just walk back to the bed and I find him asleep strange lol) and has done this rarely for about 6m. I have a 21m and she is no where near going to sleep in her own.
I always tell myself someday they won't want mom laying with them so I try to cherish these days, but on nights like last night where it took 1 1/2hrs because they were overtired it's hard to remember.
