We have a one for Lewis, it's in a shoe box mind I really must get around to buying a proper one lol
We have his first babygro he wore, his little booties, scratch mitts, his bands from hospital and mine. All his cards, his first rattle just little things like that. I have his baby book too which I love! Have his hand and foot prints but he's older not newborn. Wish we got them done when he was newborn though.
