The extreme shallow depth of field is cool for some but maybe get all of her in focus on some too. It looks like you know the importance of focusing on the eyes which is great.
Always remember its easier to crop part of a photo out than to wish you hadn't cut off too much.
Well.. always leave enough room around the subject just in case you want to crop it to get a better composition (or just get it right the first time). You also need some room just in case you frame it. You dont want the baby's head get cut off by the frame.
