What have we started?

So my last post told you Rainey loves to hold Aden. Well, the next night as we were winding down, getting ready to watch cartoons, I sat down next to Rainey holding Aden and Rainey began to fuss. He wanted Aden in his lap again! He doesn't move an inch when he's holding Aden. The video shows him giving kisses to his little brother. I can't say enough how sweet he is to his little brother. He is going to be his protector!!
