My daughter has tubes, which she received when she was about 10 months old. She is now 21 months old and she is a chatterbox.
She has about 20-30 actual words, she has her own baby babble that she uses quite frequently and special words that consistently mean certain things. I've been told by my dr that this is normal so I wouldn't worry.
Tubes are great - we had 3 months of solid ear infections after ear infections. It was awful, but since the tubes, we have had no ear infections! Woo!
As far as tubes go, our dr said we should use them religiously but as Hazel's ears were so small, even the infant-sized plugs cut in half were too big and getting fitted earplugs was a joke for the price and how often we would have to get new ones.
We just are really really careful about things like bathtime and swimming. We try to make sure she doesn't immerse her ears in water and use a pitcher to rinse her hair with our hands cupped over her ears. But if she gets water in them, we just watch the ears for drainage for a couple of days.
Good luck!
