I would not be too concerned. I mean one scenario is she might find out later she is on the spectrum, but she might not. Do you think you might offend her if you suggest she talk to her pediatrician about possible developmental delays? My son at that age only wanted to jump! Jump on a trampoline. Jump using one of those balls with handles. Jump off the couch. He also was obsessed with water, drainage ditches, culverts, etc. My friend's son was raised in a bilingual home where dad spoke only English and mom spoke only Chinese to him. He was extremely behind at age 3 and 4. He barely spoke and when he did it was not well. In 1st grade suddenly he was caught up to everyone else...AND speaking two languages fluently. Just remember...every kid is super different. One kid might be reciting full sentences at age 2 and another may not really speak much till age 5. One of my kids was a really early speaker and his best friend in preschool didn't talk much, grunted like a caveman, and had all these funny made up words. His little friend who spoke late was fine...he's a very smart teenager now.
