Welcome!!! I don't post often, but have gotten a lot out of the members of this forum. I have a second grader who is at the high end of the gifted spectrum and a 18 month old who is advanced, but no clue where he will end up😀.
Sounds like you are doing great with him and I too struggle with how to keep meeting my toddlers intense needs to explore and learn. I am probably a little more relaxed this time around because I made it through the toddler years with my daughter and so far she is turning out just fine😀 Feel free to post, I am going through the same thing😀
