Where's the time gone?

I am amazed at how much Evan is changing and how quickly.  Not sure if it was the little boy hair cut I gave him this morning, but he went from being this little 6 pound little baby to this incredibly active and talkative little boy.   While at Gymboree open play,  E did his usual crawling and tumbling up and down the play equipment.  But today was different.  Today he attempted multiple times to walk.   Each time he took about 5-10 steps.  Wobbly, of course, but he was eager to do it.   He also learned how to go down the stairs or anything that is raised off of the floor backwards.   I taught him by saying "turn around and down" and it definitely paid off because today was the first day I didn't have to say it or cue him to remember to do it.  Another new observation I made today was while he was on the wooden rocking horse.  He saw an electrical outlet on the wall to his left and said "no" as he shook his head.   As I saw him do it, I reaffirmed him by saying "no touch" and "danger".   He followed my affirmation by shaking his head no and saying "no".   E is also saying "hot" and knows when something is hot.  We were eating breakfast yesterday and Evan saw my coffee and said "hot".  Similarly as I was making dinner he felt the heat from the oven and said "hot, hot".   Oh my...and when I ask him to help me, like get the dog out from under the bed, Evan will crawl over to Dex and say "Dexter, Dexter" while patting the ground or his leg in an attempt to get him to come out.   Speaking of Dexter, when E and I take Dex for his walks, E likes to hold Dex's leash.   It took a couple walks before E realized he had to hold on the whole walk.   We'll see how long wanting to walk him lasts :0)   I know there are a few more things that he's been doing new as of late, but am stumped as to what they are.  When I remember them I will add them.
