When I had my first big boy I religiously filled in the memory book. In fact I filled in 3, as we were given a couple as gifts! This time around I am having to do bulk updates as I just never get the time to sit down and fill them in (I have 3 again aah!).
One thing I was determined to do for my small boy as I did for big boy was these beautiful letterpress update cards.
The idea of them is you send them to people with a photo but I have filled them in for the boy's memory boxes.
You can find them at Oh So Cherished. They sell a 6 month update card and a 12 month update card. (I will warn you - you may find yourself spending a fortune on this site, everything is gorgeous!)
At 90p they are a lovely but cheap little thing to store for the future! Plus you get free delivery!
