Usually boys are a little behind girls, but I have a 22 month old girl who is just now learning to say words although I know she has been understanding me for months. Do you think this boy understands what you are saying all the time?

I have a 23 month old boy who is off the charts with talking and language skills, but clueless in oh so many other ways it blows my mind. All children are different but by age 3-4 they should all be caught up and that's when to really get concerned I guess.
