I apologize that this is long. I've been saving my question for over a year, and have finally decided to post.

I once posted over a year ago, about my 12 month old son using a 3 word sentence. He held up a remote control and looked me dead in the eyes, and said "What is this"? I had asked on this forum is this a sign of of being gifted? A helpful poster suggested I read RUF ESTIMATES. I took this advice, and bought the book and gathered all the milestones I had marked down, and began to keep note from that day on.

So fast forward a year later, and my son is now 25 months old, and he could fall into category one up to category 4 of RUF ESTIMATES book? Besides getting the "aha" moments all throughout the book I felt like he could fit in almost all categories?

Here are some of his milestones i've noted

. He said Mama at 2 1/2 months super clear. His step-sister was with me, and instantly looked at me, and said did you hear that? Of course I did, but was still in shock to say anything. Almost in disbelief that it was even possible at that age.
. Says Dada at 7 months
. Says What is this? and I did it at 12 months old
. drinks from a straw at 6 months.
. Knows sounds of Alphabet at 15 months from Leap Frog DVD's
. 24/25 months knows alphabet & their sounds. Counts 1-10, knows his colors, shapes, and body parts.
. 1 to 1 correspondence at 25 months - he was taking toys off a shelf and counted 1 for 1st toy, 2 for 2nd toy, 3 for 3rd toy as he took off each toy one by one. Also likes to jump and says 1,2,3 then jumps in my arms.
. 18 months (memory) - At 18 months we traveled to our vacation home (condo) and he heard his voice echo in the main lobby hallway. So from then on when ever we walked that hallway he had to hear his voice echo. We would come back to visit 6 months later and as soon as we step foot in that hallway he yelps to hear his voice echo and keeps doing it until we reach the end of hallway. This happens every time we go to the condo usually 6 months apart.
. 25 months (memory) - we played on a merry-go-round at a park, and I kept saying my baby, my baby as I chased him. We visited the park 2 weeks later, and as soon as he got on the merry-go-round the first thing he says is my baby, my baby so I would chase him.
. 20 months (humor) - once we were riding a train and a man coughed, and my son copied him and coughed. So the man coughed again, and my son coughed again, this went on a few more times where the man noticed and starting laughing causing my son to laugh and said are you copying me?
. 25 months (intensity) - his buzz light year action figure is meant to have bent legs, but he wants them straight. He keeps saying sorry, and for me to straighten them, and is bothered every time his legs are bent and cries. He cried for the whole 30 minute car ride home because Buzz light year's helmet wouldn't shut all the way. He cried after we got home where i ended up taping the helmet shut, and eventually hid the toy in a closet because I was mentally exhausting over a toy not functioning right. He has no patience for anything and melts down when things are not perfect.
. 20 months - my nephew showed my 20 month old how to strum his guitar and hold the cords at the top. So he let my son try and my son held the cords at the top and strummed the guitar at the same time. my 17 year old nephew got a kick out of this little guy doing it perfectly for a baby, and that he paid attention on how to do it right and hold both parts of the guitar at the same time.
. 20 months old - he has watched every pixar animated movie there is. These movies are at least 90 minutes long. Shame on me for that much TV time, but it was the only break I got.
. 25 months - memorized a lot of his books and says them out loud as I read. He's also memorized his movies and says parts of scenes throughout the whole movie.
. 25 months - speaks in 5-10 word sentences. Hey dad are you alright are you ok now?
. 25 months - He Loves emotions - his favorite is "SURPRISED" at the moment where he stares blankly then screams surprise with the biggest eyes.. laughs then stares blankly and repeats this a few times laughing cause he knows this makes me laugh.
. 20 moths old - Husband showed him once how to test the water in the shower to see if it is hot or cold before getting in.. he tests the water everyday and takes a shower by himself at 20 months till today at 25 months . We trust him, and I know it seems dangerous to some people, but it's normal in our house.
. He's never touched anything that he's not suppose to. We never moved anything in our house after he was born. Friends, who have toddlers, thinks it's nuts that we have glass vases, etc in the corners, etc Never used baby gates. We put them up, but they were never shut or locked. He moved through them freely every day. He's always handled electronics with delicate hands and uses my iPhone, iPad and has his own (old) computer because he's shown that he is careful with electronics.

and last I feel a little alone - I have tons of friends with toddlers and I have slowly started to keep his accomplishments to just our family. Even though they tell me everything their child is doing.. when i do it it feels like i'm bragging when I'm just a proud parent just as excited as they are for something new my son has done for the 1st time.

So tell me is he gifted? What category would he fall into?
I feel like I can relate to so many posters on this site.

Again sorry for being so long.
