Sierra's cousin, Harmony, is 4 years old. Harmony and my sister live with my parents, so there was a lot of time for Harmony and Sierra to interact during the beginning of the week. Harmony isn't used to sharing her toys, and this is the first time she's spent with Sierra since Sierra has achieved mobility. Needless to say, it took a little while before Harmony accepted that Sierra is a baby and gets into things, especially if those things are her toys. Harmony did a lot of snatching toys out of Sierra's hands in the beginning.
Sierra had crawled over to Harmony's box of playdough and various playdough accoutrements and started taking things out of the box and setting them on the floor. What can I say? She's really into removing items from receptacles at her current stage in life. Harmony caught sight of Sierra and with sheer panic resonating in her little 4-year-old voice, she shreiked, "She's gettin' into all my important stuff!!"
Luckily, Harmony did get used to Sierra and was quite the helpful big cousin within a day or so.
