I started talking at age four, when I whispered a sentence of my own into the ear of the babysitter like I was telling her a big secret. After that, I said a sentence of my own very occasionally, like once eberry few months, until I was eight, when I learned to talk for eberryday communication. Until then, I was almost completely silent, with a little bit of echolalia, a little bit of recitation of verses and songs that I had heard, and the very occasional own-speak. No functional communication or conversation though, like telling things or answering questions. This same babysitter whom I spoke to was obsessed with epic poetry, so she spent most of our time together reading me epic poetry for me to repeat back like a tape recorder, while the other few children that she took care of at her house played with each other. iMother tells me that I was the favorite of this old lady. I think that this echo echo echo echo echo echo echo may have helped my speech development, because I said the most words in the presence of this particular babysitter, and so did being taught a foreign language eggsplicity starting around age eight. I still have a lot of echolalia, causing some embarrassing moments of repeating multiple times the words of random strangers or people I know in groups, but I just pretend that nothing happened.
My cousin was also a late talker, but after he started talking, he talked very fluently and a lot lot lot.
