My 18 month old DD has a few behavior issues that I thought were pretty normal baby behavior until my MIL mentioned yesterday that she exhibits some signs of ASD like her uncle did when he was little (he was diagnosed at 30 months). My daughter isn't very verbal. She knows like 10 words but doesn't say them very often, but sometimes when she does start babbling, she'll say the same word multiple times. She also has been getting very picky about which nursery rhymes she'll listen to and go into meltdown quickly if another plays (same thing about which books she's read). She's always been a pretty happy baby but hates to be held most of the time, even by me or my husband. When she plays with her legos, she'll pile them up in one area then move them to another then move them back (she'll go for an hour at this back and forth).
Her Ages & Stages for 18 months came back normal at the end of September, she even excels in some areas. Just not sure if this is just growing pains and she's developing more of her personality or if we need to discuss this with her pediatrician when we see them next month for the second half of her flu shot. I just wanted to get some insight from other mommies instead of family and webmd.
