  1. 1
    Cut out each template. Be very careful not to cut out any of the graphics or design.
  2. 2
    Match the appropriate template with the right onesie. The last thing you want is for “month 12” template to land on a onesie sized for a three month old! Lay the correct template on the corresponding shirt and lightly add a small piece of clear tape to ensure it stays in place.
  3. 3
    Iron shirts before adding the template. To ensure the best transfer, make sure each little shirt is flat and free from wrinkles.
  4. 4
    Add the transfer paper and apply the iron for 15 to 20 seconds. Or, follow the transfer paper package instructions.
  5. 5
    Peel the transfer paper off the shirt. Be sure to do this slowly as the design might rip off with the paper otherwise.
  6. 6
    Repeat the process for each shirt until you have 12 little monthly birthday onesies.
  7. 7
    Finished. They're now ready for wearing and photo shoots. If they're for a gift, arrange in a box as shown in the image.

I knew even before Ryder was born that I would be making him a onesie for his birthday. I mean let’s get real I’ve made him quite a few cute custom onesies. Why wouldn’t I make him one? And then fast forward 6 months after he was born, and my friend Darci opened up a cute Etsy shop, , and was making the cutest first birthday onesies and shirts. I loved her designs, so I opted to not make his and have her make him one. And then Jon found out and guilted me like no one has ever guilted me in my life. So I caved and decided to whip up a very quick and easy DIY first birthday onesie for his birthday party. I told Jon I would have Ryder wear my onesie for the first half of his party and after cake he would change into my friend Darci’s onesie. It worked out perfectly. I made this DIY first birthday onesie in less than 30 minutes!

Whether you want to create something memorable for a good friend or sister for a baby shower, or you want to mark your child’s growth, designing monthly birthday onesies for a newborn is a neat way to do either. Get your camera ready, as each month you will be able to track how the baby has grown, with the month prominently displayed on the child’s belly.
