And like with a lot things, the more the merrier.
Whether they are in their toy box, upstairs in their room, reading books or building blocks, I absolutely love to watch them play together. Yes, the older they get the more often they fight, but they also spend more time playing together. It just brings joy to my heart as I hear them running around the house, laughing as they go. I would make it the soundtrack to my day, every day if I could.
