In our family we have sibling playtime and we have independent playtime too. Here is the first time Isaac has actually joined in the fun instead of just watching. They were playing one of Hannah's silly made up diaper games, and Isaac just had to have one too! He fussed until she gave him one.
In this one, Hannah was supposed to be in her quiet time, but I put Isaac down in her room for a few minutes. He got a kick out of this. He loves to watch Hannah!
