As my baby girls get bigger, they are starting to play together well whenever big sis, Lina<3 wants to play, lol. Serena:) loves watching her big sister play. I love watching my babies interact with each other. It is so adorable as they learn from each other. When Lina<3 is in a good mood and not throwing temper tantrums, she is so sweet to her baby sister, and plays well together.
