I started a memory box for my daughter. So far I have the onesie she wore home from the hospital, an ultrasound pic, a “welcome baby” balloon, the cards I got at my baby showers, and the card we got from the hospital with her footprints and mommy and daddy’s thumb prints. Also keeping the stickers we get from her pediatrician saying her height and weight, I might make those into something later. I’m a very sentimental person and would have loved if my parents made one of these for me, I hope she enjoys it when she gets older!
