Gifted toddler - sorry long post

Hello Ladies. I would like you to be very honest with me. Am a ftm so I don't know how much a toddler should know but my son seems to know way more than the kids who are even bigger than him know. I swear I don't sit to teach him stuff. I just play with him and am always surprised at how much he knows. I dont even know if am supporting him enough. So here is what he can do.

Well today, he spelt his name. 6 letters. He can count to twenty without skipping a number or making an mistake or pausing. And he counts to 29 with some hesitance but will alternate and get it right if I sat 21, he says 22, I say 23, he says 24. Anyway. He counts from 10 backwards fast and has been able to do that for more than 6 months now but that aint a biggy because I have heard another kid's mom say they do it. He has now over 500 words. Has once spoken a 4 word sentences. He focuses so much and has an attention span of maybe 30 minutes where you cant get him to do anything else. He can do some painting, dancing, for longer periods while allowing to be interrupted or multitasking and engaging in conversation. He has a great memory too.i know at this age they are imitating everything we do and so that doesn't shock me but the precision makes me wonder. Don't call me a child abuser but today I was cleaning the kitchen and the dad was just standing around waiting for the mail. We had to leave but it was 5 stops away. Anyway. I kept myself busy, but to challenge my husband, our son came to me in the kitchen to engage me so I took his hand, we went to the bathroom to pick a laundry basket, brought it to the sitting room and I showed him to put the laundry that was laying on the couch into the basket with just one cloth by picking it up and throwing it in and didnt give further instruction. Then i left. 5 or 10 minutes later I peeped and saw he had put all clothes into the basket and was left with 2. It was so full some would hang over and he went over them twice or thrice just to get them all in. I was proud and impressed. He has helped me around the house before but never alone and unattended. It aint about doing the laundry but the concentration, precision, and patience he put into the task that blew me away.

Anyway. Back to the intellectual stuff. Well what can I say. Counting alphabet, colours animals reading attract him more. He master the alphabet, phonics, colours, animals and their sounds, about 8 months ago, actually sometimes I think it is redundant so I have thought instead of exposing him to more stuff for bigger kids, maybe he should learn everything he knows in another language instead of new stuff. But it is hard for me to teach him another language. An interesting thing would be reading. But isn't that too early? I don't want to take away on his childhood. He already can spell even 10 letter words letter by letter. I dont want to push him but dont want to hold him back. I don't want to talk about the games and puzzles he does because I also think that is also done by many kids. Sorry this is long. Am just looking for advice. Should I contact someone who can help teach me how to deal with a super intelligent kid or just swing it? Do you guys think he is gifted or just normal?

Disclaimer. Everything he learnt, he learnt after 13 months. Before then, he maybe spoke 5 words and didn't even crawl. He took forever to catch up but once he started, I feel like his growth has been exponential. At first I used to track it but now, I can't keep up. So I stopped journalling his progress. Many people tell me they haven't seen a child like this. Today, hubby got teary as our son spelt his name for him to write. It is a game they play. He says a letter, and a word for it and hubby has to write and draw it. They started 2 days ago and today he pushed him to write his name. Which got me thinking. Maybe am not supporting him enough. Giving him enough challenge and need to seek programs that don't take away the childhood, but help the child reach full potential. Ps. My husband is also super intelligent ( been top of his class since first grade to his phd) so maybe the apple doesn't fall far from the tree. Me, haha. Am not super intelligent but smart enough. Growing up, my husband and I were brilliant and we got the best our parents could offer which was ok. We still made it but it wasnt the best there was in this world. But we can offer our son even more to support him as he aint limited by surrounding or finances or a lack of interest from us. And I want to max out his potential. Just dont know how. Where is the balance between teaching and playing. I want him to choose to become anything he wants, but also I think he can only become what I expose him to so I try to expose him to a lot. But how much is too much? Where is the balance between following a passion and being pressured. Right until now, I have let him lead me to what he wants. He will take me to read and I will do just that. If he wants to count we count. I dont teach him new stuff. Just go over what he wants to repeat and I think much as this approach keeps him safe from me pressurising him, I may not be doing a good job offering Challenges and teaching him. Maybe he would know more than he knows now. I dont know. What do you guys think? I feel like this was a whole therapy session.
