D.!! we have so much in common!! if you ever want to chat further please contact me.
my son is 25 months & my MIL has been calling him 'severely speech delayed' since before he was 2. what upset me even further was she almost came out & called him stupid based on the fact that he's not talking. she couldn't believe he could do advanced puzzles & pick out a fire truck vs an airport fire truck from a picture book. (i could go on).
i asked my son's ped. at his 2 year wellness check about his lack of speech & she did refer me to 'help me grow'. i have begun the process but have yet to have my son evaluated. they're a wonderful org. & a good friend of mine went through the whole process with her oldest son. it's all free of charge & they help you until your child is 3 & then i think your school district steps in after that. help me grow determines your service by the county you live in. when you call, they'll ask you which county & then tell you who to go to.
it's funny, my mom is the total opposite of MIL. my son is #7 grandkid for in laws & the one & only for my mom. i don't think my mom even wants him evaluated!!
anyway, my son has only single words - no sentences. however, everyone (esp me) in his life overly interprets for him. he'll point to something & go "hmmm" & i'll say, "oh, you want those crackers?" & he'll say, "yeah!!" i'm trying to get better about asking him to actually tell me what he wants. he may not talk much, but he has been dribbling a basketball since before he could walk, he follows compound verbal directions (go put your cup in the sink & then get your shoes), he can do puzzles kids much older than him cannot, etc. also, my husband & i didn't talk until we were 3 so maybe it's genetic.
i have a feeling your daughter is just fine. i also agree with what all of the other moms have written. but help me grow is free, so why not take advantage. like someone else wrote, if they tell you your daughter is right on track then you can tell your mom she was wrong ;-)
p.s. is there a possibility of a hearing issue? we may go down that road with our son (depending on what insurance covers).
