First time Garrett meets his cousin Wyatt

This is the first time Garrett meets his cousin Wyatt when Garrett was three and Wyatt was eight years old. They came to visit for one week right on Wyatt's birthday. We celebrated Wyatt's birthday at nana's house. They played together so well for the first day. Wyatt chased Garrett run around the house, the laugh and had lot of fun. But three days later we meet Wyatt again at his birthday party. they are like stranger. and dont play much. It is just Garrett. He is so shy sometimes.
