Callie has been getting good with her standing skills. She will let go and can stand for about 5 seconds by herself. The only problem is she thinks someone is always going to be there to catch her and she tries to walk away, except she can't walk without her hands held.
She has also been starting to stand up using objects. I wouldn't exactly call it a pull to stand. She needs the perfect height and shaped object, her favorites are your leg or the bathtub edge.
Either way she is getting good fast and it's only going to be a short time before she is running all over the place!
