We got this book for our daughter who will be nearly 2 when the new baby arrives. I think the illustrations in this book are cute and I am especially pleased that the new baby is shown breastfeeding twice in the book. Also when they are out for a walk the baby is in an ergo type carrier, which is also neat. I mention breastfeeding because it seems that bottles are commonplace in other new baby books and aren't relevant to our lifestyle and I was specifically looking for a book that would show an infant nursing so that I can explain to my kiddo ahead of time that she'll have to share the breast. At first I thought they were cosleeping too, which would have been even more perfect for us (the first two pages they are all in one bed) but at the end of the book you can see that the baby sleeps in a crib and the toddler in his/her own bed. This isn't a criticism or anything, just mentioning it in case someone finds this info useful.
The text goes well with the pictures, I think, but it's not really a story. In a way I think the pictures are better on their own, you can come up with your own story instead of what's written. The book seems to follow a day in the life of a family, first everyone is hanging out in the parent's bed, then they get dressed, visitors/gifts for baby and toddler, taking pictures, eating/nursing, reading/singing while baby naps, going for a walk, going potty/changing diaper/crying, taking a bath, going to bed.
