2 1/2 Year Child Repeats Question Instead Of Answering. Not Interacting With Others. Concerned
Congratulations on being a very lucky grandmother to have such a bright and inquisitive grand-daughter. I have read your question in detail and think that she is absolutely normal. Repeating the questions of the opposite person can be normal behaviour in this age group and is referred to as "echolalia" in the medical dictionary (echo= sound returning, lalia= speech).
Actually, the child may be playful (especially if you see that she is giggling or laughing as she repeats the question), or, more likely, she is learning the intricacies of English language and acquiring skills of articulation and voicing, diction and inflection. Thus, after a few months to a year, as her skills increase, she will outgrow this "problem" and speak fluently and easily.
You may help her by listening to her repeat the question, and then voicing the appropriate answer for her as a prompt, so that she will repeat that, too, and improve the command on her language.
Persistence of echolalia can be a symptom of psychological problems, but in your case, it seems to be entirely normal at this stage/age of her development.
Her liking for younger children and staying away from older ones or peers is again nothing but an individual preference, and should not ring alarm bells in your mind.
If you have anything more on this or need clarifications, do revert to me.
Thank you once again for addressing your concerns on XXXXXXX
With warm regards to you and the baby's parents, and love to the child,
