After their bath tonight, I put Emily in Abby’s hooded towel and used a regular towel for Abby. Since Em was in the hood, Abby couldn’t see her. So, while I was drying Abby off, she was craning her neck to see what was in that towel! She really wanted to know and would not let me finish drying her off before I uncovered the secret within… her sister!
Once she knew, she was happy again.
