Awww... those are my favorite times of my life, when my son was little, learning, curious!

My 'baby' will be 29 in a week!

One of our favorites was "You Are My Sunshine"

You are my sunshine
My only sunshine
You make me Haaaapy
When skies are gray
You'll never know, dear,
How much I love you.
Please don't take my sunshine away.

here's one I have modified as I got older:

Thirty Days hath September poem

Thirty days hath September,
April, June and November;
February has twenty eight alone
All the rest have thirty-one
Except in Leap Year, that's the time
When February's Days are twenty-nine

my modified version is:

Thirty days hath September
All the rest? I can't remember!
