Since my kids are worlds apart in attitude they each do something different to make me laugh.
My Mackenzie, is extremely smart and loves to dance, draw and play with anything that is not one of her toys. I find myself laughing when she takes something I say literally. Just recently my husband took the kids to the lakeshore to play for an afternoon. When I got home from work (around 5 pm) my son was still sleeping, which is very unusual for him. Mackenzie was awake and playing with something when I looked at my husband and said, "You sure did poop that little man out, didn't you." Without missing a beat, Mackenzie looked at her father with wide eyes and said "Daddy, you pooped out a little man?" I was crying I laughed so hard!!
My baby Alexander, we call him Xander, is my cuddler, my Mommy's boy and my screamer. I can usually get him laughing to get him out of bad moods by giving him silly kisses on his face and neck. He learned to reciprocate, so whenever he thinks that Mommy is in a bad/sad mood he will come up to me, grab me by the ears and give me silly kisses on the face and neck. I laugh every time!!
