Monster First Birthday Shirt


My monster first birthday shirt is the perfect accessory to show off surviving a year of parenthood. You made it! The best 1st birthday shirt:

  • Has a unique design your kiddo will look extra adorable in.
  • Is something they can wear for more than one day.
  • Has a long, slim fit, since your child isn’t square-shaped, thank you very much.
  • And is a neutral color that easily pairs with their monster PJ bottoms, baby jeggings, and that backup pair of bottoms in the depths of the diaper bag.

Snag your little one’s size below before it sells out (and cross off one more pre-party task)!

Ready to ship in 3 days or less. Free U.S. shipping for all Yippitee shirts!

NOTE: there are no toys on the shirts for children under 3.
