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.

Ready to ship in 3 days or less.

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