Adjectives to describe Caleb

What adjetives would I use to describe Caleb?

Active, Stubborn, Observant

Now lets look at each of these words a little closer

Active:

• He is always on the move. Even at a month old he was constantly moving his legs.   He preferred to be held while you were standing and walking around the house.  His favorite place to hangout was his bouncy seat, and you had to give it some extra bounce.
• Caleb is crawling everywhere.  Just this week he has started crawling into rooms where neither Chris nor I are.  This is exciting an a bit scary.
• I think Caleb would rather be standing than doing anything else.  All he needs is something taller than him (preferably something sturdy) and he can find a way to get up, either pulling himself up or leaning while getting his feet out from under him.  Unfortunately he is becoming pretty bold with standing up and he will be on his knees and lean towards something to help him get the rest of the way up.  The problem is he does not always realize how far away from stuff he is and he falls on his face.  Of course he doesn't know how to catch himself yet.  Oh and he usually has a toy in one hand, with the other hand outstretched to lean on something
• Caleb can now climb up stairs.  Holy Cow.  It turns out all he needed was some motivation.  We have two sets of stairs in our house from the main floor to the second floor.  The set that is most often used lands in the living room aka the play room.  So Caleb has been around these stairs and seen Mom, Dad and Max use them plenty of times but was never interested in them.  Until we moved Max's dog food onto one of the landings (two stairs up before a 90 degree turn).  Caleb is obsessed with the dog food and bowls. Yesterday I look over and Caleb has climbed one stair and proceeds to continue climbing until reaching his destination.  Later Chris wanted to see him climb so he was encouraging him up the stairs and it was a no go.  Until I climbed the other set and stood at the top talking to him.  The little man climbed all the way to the top (only two hours after learning to climb).  Wow I was impressed

Stubborn:

• So I already mentioned the dog food.  Caleb has been crawling toward the dog food and picking it up, dropping/throwing it everywhere, eating it, and best of all dumping out the entire water dish.  Oh so much fun to fill up.  It doesn't matter how far I move him away from the dog food he immediately goes straight back there.  We have been conducting a bit of an experiment by blocking him from the food and boy does he get mad.  Throws his own little hissy fit.  
• The blinds.  Oh how annoying it is to have a baby pulling and banging on your wooden blinds.  I can't really blame him for wanting to play with them, they are interesting. The blinds scenario plays out practically the same as the dog food.  
• Max and Caleb play with the same toys.  I tried to keep them seperate, but Max kept picking up Caleb's toys and then Caleb started picking up Max's toys and well I just gave up.   They are kept in different locations (assuming i picked them up for the day and they are not scattered around the house).  On occasion Max has taken a toy out of Caleb's hands, and he does not like it.   He starts crying this sad frustrated cry, until he is distracted by a different toy.
• Hmmmmm so many more examples but I am drawing a blank

This was before I realized it was going to be a problem.

Observant:

• Caleb is always looking around, checking out his surroundings.  
• He has started noticing things above him, which is a bit more interesting when you consider he is never laying down, and certainly not on his back.  
• When we go to a new place, he is checking out everything so he rarely smiles.
