Getting too old?

I went to the picnic celebration today for Ethan and Logan at the TLC. Ethan has just turned 5 and already ignores his parents when in public! When do they learn this?! Ethan would not wave to me as he ran by playing with his friends. He would not give Nonny or Rachel hugs. He was just TOO good for us! I did not know that this started so early in life! At least Logan was still excited to see Daddy. It makes me sad that Ethan is growing up, but I am glad that he is making friends easily.
