Anyone keep a memory box for baby things? What have you kept in it? We didn't, wish I had. Wondering about this m.johnlewis.com/john-lewis-silver-plated-photo-frame-keepsake-box/p/2031493 for a gift for a new mum but wonder about size, guess it would be great for a few things like hospital band but would a bigger box be better so could include first babygro etc?
