That's what we all have and at times that can be a bit confusing. The little man likes doing maths with his daddy. 2+2, 3+1, 4+2 and so on. Nice easy maths where ten fingers are enough to count and work it out. Yesterday daddy asks the little man: "What is 10+1?" Hmmm, not sure what to do so he looks up at his daddy and says: "But I only have 10 fingers...!" Daddy lends him one of his fingers and after counting them all, a very loud 11 is shouted out! The pride on the little man's face was priceless!
