Not always so happy together

The girls have just started to play together.  They have always 'played' together but now I mean that every so often they will actually play together in the same room.  Play in the same room, together, and don't need me by their sides.  (Not much but every so often...)  Yesterday morning the girls were doing puzzles in Hannah's room.  I heard Hailey squealing a little and then walked in to see this....

Hannah was laying on top of her saying "I love you woman!"
