"Playing House" Together

I caught Ellie and Charlie happily playing together again yesterday.  It's amazing to watch them grow as siblings; they've gone from mostly playing side-by-side to now sometimes playing with the same toy and interacting a bit.  I really do hope they end up as good of friends as my sister and I are.  I'm so not looking forward to that inevitable stage all siblings go through, though, of constant bickering, "Mommy, she's touching me"- issues, etc.  Already, you should see Ellie slap that hand away with a blood-curdling screech when Charlie innocently reaches over to touch his "sweet" sister in the car!  We're off to a fine start.
