Suggestions Please!

So I have been really into scrapbooking again. ( It comes and goes) I started working on a baby book/ scrapbook for the baby. I am making it a baby book like you buy in the stores. I have made a few pages already and need some ideas for more things that you would find in a baby book. If anyone has ideas for any firsts or things I may want to keep in this memory book I would really appreciate any and all suggestions. Thanks a ton!!!
