I think Whitney thinks the girls that I babysit, Emma & Audrey, are her sisters. She loves them just like she loves her own brothers. This morning I was cleaning up after breakfast and found Whitney saying "Hello" to Audrey. It looked like she climbed on the chair and then pulled herself into Audrey's highchair all by herself! (Audrey doesn't seem too thrilled.)
