Memory baby books

Elizabeth • Mommy of one beautiful girl, and twin boys (:
I don't know how many still do this, but I want to get baby books for my boys. The ones that go to the first five years. I have one for my daughter, and I fill it out when I have the time. We have social media now to keep track of everything, but I love baby books because they make adorable, personal gifts for when our children get married or whatever occasion you choose. Would you get one for each baby, or would you put both in one? I thought about getting one for each. Would you buy the ones that you just fill out, or personally make? Like a scrap book? I'm half tempted to do scrap book and then make one for my daughter as well. Make them just as unique for each child's personality throughout their lives. But I would go to the age of 18 and not just 5. Or do both scrap book AND baby books? I'm so lost lol.
