Our youngest son is almost 20 months and he doesn't talk, I'm worried, but his Doc says it's okay. He babbles in baby talk non stop, he can say mama, daddy, bubba, eat ( of course lol! ), hi, ewww and a few others but even those words he rarely uses.

He seems just fine in all other areas, he's very active, into everything, running, walking, climbing, throwing tantrums ( he's good at this ), yelling in baby babble language, and he understands most everything I say, but shouldn't he be saying a lot more? Our oldest son talked non stop right away when he turned one so am I just freaking because this little guy is developing differently?

Any tips or suggestions on helping him along?
