19 month old milestones?? ?

My son will be 19 months old on the 3rd, i was just wondering what milestones he should be reaching.. I know all kids are different, but whats the average.. Im not worried about anything, his daycare/preschool teachers tell me hes quite advanced.. Heres some things he can do.. -- Say basics like mommy, daddy, kitty, doggie, baby, car, tractor, truck., juice.. If i show 2 pictures of a cat and dog he can tell me which is which.. Runs Jumps Dances Will say "Pwee"(please) if he wants something.. Climbs Knows the difference between all kinds of things and will bring them to me if i ask him, like phone, remote, brothers pacifier, wipies, diaper, and so on.. I just want to know when he should start putting words together, like, "Bye mommy"
