La Texican...love the pic!  My kids have always sucked on lemons from our water at restaurants (probably to please Daddy).  Your DD sounds amazing!
I had to make a brag today.  I have several friends with boys 1-2 years older then my DS5.  DS had had his fair share of getting the 'little brother's treatment.   Yesterday, I overheard this conversation between the 7 year-old and my DS.
"You're still a little kid."
DS:  "No I'm not."
"Do you know math?"
DS:  "Yes."
...and then DS was quizzed on a myriad of math equations.  He answered 
them happily and not smugly...but got every one correct (go DS!).
"OK, you do know
w math."  And the little twerp walked away
