List of Baby's First Birthday Stuff This list of baby’s first birthday stuff has some outfits and more. You will find outfits for girls and boys. I also found some first birthday board books, first birthday photo backdrops and a few other things. My grandson’s first birthday is in May. It seems so crazy how fast time is going and he is growing! If you are preparing for your baby’s first birthday, I hope you will find this list to be helpful.
