Think my just turned 3 year old may be hyperlexic

[Rockean]

After posting on the AIBU about my DS previously, I have been researching about hyperlexia.
I’m pretty certain he is showing clear signs of it. He is constantly lining up his magnetic letters and from the moment he wakes up that’s what he wants to play with, nothing else.
He’s only just turned three and can write his name, write words either through sounding them out or through remembering them written in a book or something (his memory is fantastic).
He can sound words out perfectly e.g. yesterday he said “S-L-U-G Slug” and then phonetic sounds were exactly right.
He seemed to teach himself a lot of it from Alphablocks on CBeebies.
He can put letters in order to write out the alphabet.
He doesn’t want to play with anything else except his letters, so no imaginative play or anything like that.
If we get the playdough or blocks out, he’ll make letters with them too!

But his speech is excellent and he’s very sociable and confident with other children and adults.
So I don’t know what to think!

Hyperlexia is the presence of very fluent and accurate reading skills but very poor comprehension. Often characteristic of children with autism. It does not sound like your son fits this profile. He just sounds like a normal 3 year old

I don't really understand your post.
DS is hyperlexic (reading and writing before 3) and didn't speak until he was nearly 5. I didn't know he was anything in particular and spent hours doing crafts and imaginary play with him. He was always top of everything at school so we didn't bother with school work and focused on team sports, gymnastics looking after our animals (we have a farm) and musical instruments. He's a well rounded very popular young man now. At Oxford doing a very 'ready' subject and having a great time with his friends. We always bought him any books he wanted but encouraged comics and magazines etc too.
It's just part of your child, I would focus on his physical and social development and aim for him to have a more balanced range of play. Lots of silly, funny books and then games based on them but use imagination is a good starting point. The most important thing is that he is a happy child, why are you worrying?

I saw your thread www.mumsnet.com/Talk/am_i_being_unreasonable/4368398-My-just-turned-3-year-old-can-read-and-write?msgid=111435121

and with the description on there plus his fixation with letters and no imaginative play as yet, I'd consider keeping an eye on him for any other neurodiverse traits that may or may not show up in the future.
Things like see if he plays with other children or plays alongside them, does he have any sensory issues.

Don't let it become fixation for you to find differences between him and his peers though, enjoy spending time with him and enjoy seeing the world through his eyes, small children are fascinating to be around and in the blink of an eye, they're at school.

Hmm I think my daughter may have had this too, she came into the room with a letter at 2 years old and said "this is from powergen" it was, mind. Freaky wee child.

It's just a thing though, some kids are like that. Apparently I could speak at 8 months and read super early. It's just a thing, encourage reading but it doesn't mean much.

I got pretty good exam results and was obviously pretty clever, also had many defecits on the social side of things.

I don't think hyperlexia automatically means terrible comprehension either.
