Ross has some words not a ton though. He "talks" all day long but i understand very little of it

Like Tommy he understands what others are saying to him, and can follow simple directions (if he chooses to listen)
dont worry too much yet, at this age the "normal" range for vocabulary is huge. I used to nanny for a family who had a young son, and honestly he only had about 10 words at age 2, and you really couldnt understand him until closer to 3. Hes since caught up and he is a happy healthy 6 year old, he just didnt have anything worth saying i guess
