Daddy (daddy): He says this perfectly and quite well. I am impressed.
Hi (hiiiiiiiiiiiiii!!!!!!!): accompanied by a wave
Baxter (Basher or Dasher): this is the dog. He says it more than mama....
Ball (bob): this may be the word for all toys now?
See (see): this means "can I see?" or "do you want to see?" which we ask him often. Or maybe please...
Thank you (thisshew): anytime he gives us something, accompanied by a proud smile
Baby (babum): this is very hit and miss, however. For his baby doll.
"Uh!!!" seems to serve every other linguistic purpose currently.
