Aidan calls me Princess!

Today Aidan woke up on the "right side of the bed", he was in good mood. When I carried him out to the living area, I told him "The Prince is up, the Prince is up" and he repeated after me. After I changed into my office attire - a red n white dress, Aidan said to me "Princess". I was surprised cos I have never said this word to him before and I asked him who is the Princess and he replied "mummy". Aidan, you have made my day today :)
