My DD is 22mo and she is very communicative and chatty, she has around 100 words and is starting to put two together, and is learning more every day, but she still doesn't really respond to her name. Not consistently anyway. She generally will look if I say her name followed by "look!" or if I'm offering something like food, but I could call her name until the cows come home and she wouldn't look.
She has had a recent ear infection, and had some fluid behind her eardrums which could be affecting her hearing, but of course in these pandemic times I can't get a hearing test for her for six months. But having said this, her response to her name has always been patchy at best, even before the ear infection. She generally doesn't look at me when I'm talking to her either, but has good eye contact and uses plenty of gestures to get across her wants and needs, and to share attention. I've noticed she generally doesn't respond to loud noises either, and doesn't really respond when I ask her something - although she will sometimes, especially when I'm asking if she'd like something to eat!
She can be quite repetitive in the way she plays, she likes to play the same games in the same way, but she does play appropriately with toys, and doesn't show any obsessive behaviours. She does have some repetitive hand-flapping behaviours when she's excited, and has recently started covering her eyes with her hands when she knows she's doing something she shouldn't.
Has anyone had experience of this? Everyone tells me I'm mad to be worrying, but of course Dr. Google has already diagnosed her with autism 
. I have spoken to a good friend who is an SLT and she isn't overly concerned, but it would be lovely to hear from others whose little ones had similar tendencies and how they have developed as time went on.
