My son is 5 (almost 6) and he isn't talkative much. Really laid back and just goes with it. Me, the wife, and him can be all quiet and kinda do our own things but it's my daughter (3 almost 4) that's the talkative one. SHE WON'T QUIT! She just talks and talks and talks. Even when no one is talking with or to her. She is like having 10 kids alone! My son is fun to take fishing/hunting because he's quiet the majority of the time. He's even shushed me on the fishing boat because he said me talking will scare away the fish!!
Enjoy it, time does go by so fast..............
EDIT: Oh, and quit watching the vampire movies! LOL!!!!!
