I woke up to this beautiful boy VERY eager to tell me "Happy Modder's Day!" After handing my his artwork, he excitedly told me Happy Mother's Day several times.
In fact, he was so excited about it all, every time he would color a picture within the next week or so, he would hand it to someone and say "Happy Modder's Day, ____!" He told his daddy several times, "Happy Modder's Day, Daddy."
I'm guessing that means he didn't get the concept quite yet. I'm also guessing that just means I will get a "Happy Father's Day, Mommy!" AND that - I am very much looking forward to :)
