I am starting to get concerned about DD's (about to turn 9 months) language development. I know that all babies develop on their own timeline and blah blah blah, but I'm starting to think that something might not be quite right.
DD makes lots of noise and is very 'vocal' but is not babbling. For example, she says a lot of vowel sounds, rasberries, coos, squeals, etc. In the last two months or so she's started to *sort of* make consonant-like sounds. So she can sort of do a muffled 'b' sound. She can make sort of a muffled 'mmm' sound. No 'd' or other consonants. No clearly combining consonants and vowels, so no 'ba', da', 'ma', etc. I may have heard her say 'ga' at one point but I'm not sure. She does say 'hoooo' and 'gooo' but I don't think those really count because they sound more coo/vowel like. Definitely no repeated 'syllables' like ba ba ba or whatever.
The kicker is I went and started watching random you tube videos of babies and realized DD doesn't sound *anything* like babies of her age. I looked at videos of 9., 8, 7, and 6 month olds - she doesn't sound like them. She sounds more like 4 and 5 month olds. I also looked at the ages and stages evaluation for 9 months and she would score a zero on the communication part because of the lack of babbling and some other stuff.
She *does* wave, point, and clap. She usually responds to her name. She does not seem to recognize any words as far as I can tell and has never said anything at all word-like. Her development in all other areas is normal.
Thoughts? Do any of you have a baby with slow language development? What is going on?
