I have a two-year old who is fully convinced that he is four. Ask him how old he is, he answers "four." No you're only two you say, "no, I four," he replies. There is nothing, and I mean nothing, that his actual four year old brother can do that he can't. Jackson climbs up the big slide, Trey is right behind him climbing up. Jackson walks, Trey demands to get out of the stroller and walk beside him. Jackson opens a door, and we have to wait for it to close again so Trey can push with all his might to open it himself.
While cute, this phenomenon can also be terribly annoying. Needless to say, while he can do a lot of the things his older brother can do, many he can't or worse, shouldn't. Like at the amusement park when Jackson climbed up the 40' bounce slide and my little one was right behind him every step, then launched himself down in a terrifying flip which turned every head in the park in my direction with their disapproving looks. Or when he saw Jackson jumping off the side of the pool into the deep end and immediately followed suit without considering the fact that HE DOESN'T KNOW HOW TO SWIM!
The sad thing is, we are missing so many of the cute firsts that we enjoyed with Jackson when he was two. Trey just skipped them! No cute pictures of this kid in an inflatable dinosaur at the pool, he'll attempt to navigate the waters on his own. No watching Chicka together on Sprout, he jumped straight into Nickelodeon. No hearing Trey start to put words together, he went straight into full sentences. My husband summed this up over the weekend with the following comment said almost tearfully, "we'll never get to hear Trey say toot, he went straight into fart."
Enjoy it while you can!
