R is 17 months old and just really starting to have some words. He says mama, dada, ball, bubble, bye bye, binki, up, that, car, bus, dog, balloon, uh oh, water and a few others. But a lot of his words I only know what they mean. Like bus he says "ba" or binki he says "bay" and up he says "uh" and dog is "da." He also calls a truck a bus "ba." It's like he says the first syllables of a lot of words but that's it. It's hard for me to remember DS1's language at this point, but I feel like his words were more like real words at this point? Maybe not? Is this normal for first words? I'll ask at 18 month appt but I'm wondering if this is something to be concerned about.
