I have about a dozen books of sewing patterns for kids/babies. I buy them in fits of inspiration, make one thing out of each (if that), and never do they leave the bookshelves again.
The exception to that rule is Lotta Jansdotter's Simple Sewing for Baby. I think I've made about half the patterns in that book over the course of the last 4 years. They really are "simple" as the title promises, and they're for things you actually use with a small one. I made four or five of the patterns when the Kid was little, and I went back to the book again before Little Miss was born to make a few more.
[Four pictures is probably overkill. Forgive this new mama enraptured with her babe's every expression.]
Number 1: the boppy pillow. I know that opinions differ on what are "essentials" for a new baby, but this is one for me.
In the weeks after birth, you can use it to sit on yourself (so as to cushion your tender ya-ya). It works well for its intended purpose of bolstering the baby into the right position to eat. And last, but not least, it's a nice prop for when baby needs to sit up a little to get a change of scenery.
Oh, yes, and it helps with picture taking, too.
Number 2: a trio of reversible bandannas. So much cuter than the quintessential bib for catching baby drool, spit-up, whatever. When the Kid was small, we used store-bought bandannas for this purpose, but I wanted Little Miss to have something...well, prettier.
[Another instance of at least one too many photos! Oh well.]
As you can see, they're a little big still, but not for long, I'm afraid!
