4

This 4 and almost a half year old :

. . . decided that last night he didn't need the sides on his bed put up.  So he slept, all night, like a true big boy.   sniff

This little darling has, 4 of the last 5 nights, removed his pants at some point before he fell asleep.  And one of those nights, his diaper as well.  That was a LOVELY surprise the next morning.  {I'll let you use your imagination here.} :

And this little munchkin is 4 weeks old today:

Seriously.  How is that possible???
