I walked over to his room to check on him, and this is what I saw....
****Notice the rocking chair pushed up to the side of the crib - That chair is usually in the hallway - where I do time out for the girls when we are upstairs.********
I heard Tanner's mobile going, and looked in the crib and saw - Lindsey!!!! Loving on her little brother. She loves him so much!!! I said, with a smile, "Lindsey! Did you climb up there?" and she said, "yes, Baby Tanner was crying!" She had to turn him over - he sleeps on his stomach - and scoot him towards the mobile. She accomplished all of this without making Tanner cry, and much to my surprise, he was happily content with Lindsey snuggling him and watching his mobile with him. Lindsey really dose love Tanner, and she makes quite a great big sister!
