Re: Delayed walking and development question..
Personally I would get an evaluation through Early Intervention. You don't need a referral from your doctor for it so just find the local office and give them a call. "They" say that not walking by 18 months is a "red flag" and he may benefit from a little bit of physical therapy to give him a boost in the right direction.
