A baby blanket crocheted by you would be the best thing, as it is something she and the baby can use right away, and that the baby can have for the rest of his life! So if you make it kind of larger, so he can still have it on his bed when he's older, that might be very special to them both. Of course make it out of something easily washable! And you can then put a hand-decorated picture frame wrapped inside the blanket, for her to put a photo in, and maybe Cam can even help glue something on, and make a temporary picture to put inside it, too!
