I had an Anne Geddes pregnancy journal with each of my first two children. I haven't filled in all of either of them but it's nice to have some thoughts and memories written down for the future. And to keep the different pregnancies clear in my mind! With Isaac, we also took a belly photo every week from about 20 weeks onwards but I still haven't done anything with them yet! A friend of mine had The Belly Book by Amy Krouse Rosenthal for her pregnancy and it seemed a great choice for my next time round.
