I have a DD4 who has alway done things pretty early, and a DS who is now 20m. And a DD8weeks. The DS has followed A more typical pattern for the most part, but this morning we were at a child care thing and he over heard the preschool class counting to twenty. When the lady paused at 18 he finished her counting clearly and said 18, 19, 20.

DD4 is into counting to 100 and finding 100 of things, DS20m counts with her, but we can't understand what he is saying. I sometimes ask him to get diapers for our 8 week old and Ill say can you get me 5 diapers, He will bring me 5, but a few minute latter he will bring 5 more. So I do not know if he understands 1:1 ratio or if it is just copying his sister.

Also last week he was playing with his cousin with magnet letters and we relized he knows all the letter names and alot of the sounds they make. He is not really verbal yet so it is hard to see what he knows, but I have a feeling once he starts talking he is really going to surprise us.

DD4 was conversational by 16 months but she tends to talk for her little DS most of the time so he is pretty quiet. They sure are cute and I am excited to hear what our DS has to say some day.
