My boys both needed a pillow in their crib by about 8 months. It helps them be able to be propped up if they get congested. If you're worried about a suffocation risk put the pillow UNDER the sheet so it's pulled taught. As long as a child can roll and crawl and get out of a blanket while you're watching they should be fine in their bed too. :) Guess I'm the only one letting them have these things this early but we've never had a problem. Also my youngest loves going to bed so much he laughs as we put him down. I've even had friends and family listen on the baby monitor- he laughs and giggles every time. It's hilarious.
