Reviews from our Cozy Grump Fam 😌🎄

  • Baby in My Cozy Grump onesie sitting in front of the Christmas tree

    ⭐⭐⭐⭐⭐ Christmas card, done in one shot — “Sat her on the rug in front of the tree, flipped the hood up, and she gave me the exact grumpy face. Took the picture, sent it to the family group chat, and got 40 replies before dinner.” — Danielle R.

  • Baby in My Cozy Grump onesie at Christmas dinner with family taking photos

    ⭐⭐⭐⭐⭐ Every relative took the same photo — “I counted six phones pointed at him at once. My father-in-law has never taken a photo of anything and he took this one.” — Tasha M.

  • Baby in My Cozy Grump onesie lying in a crib with felt claws out

    ⭐⭐⭐⭐ Photos are perfect, zipper needs a snap — “Got the crib photo with the little claws poking out and it is my lock screen now. Four stars because I'd like a snap flap over the zipper at the chin. Fleece itself is so soft.” — Kelly B.

  • Two babies in matching My Cozy Grump onesies on a couch

    ⭐⭐⭐⭐⭐ Cousin twins for the Christmas photo — “Ordered two so my son and my sister's baby matched. Best picture we have ever taken. Both hoods stayed up the whole time.” — Andre P.

  • Baby in My Cozy Grump onesie by the fireplace

    ⭐⭐⭐⭐ Roomy, so buy true to age — “Photo by the fireplace turned out great but he is 7 months in the 6–12 and swimming a little. Worked out since he wore it all December.” — Megan L.

  • Baby in My Cozy Grump onesie with laughing grandpa on the porch

    ⭐⭐⭐⭐⭐ Grandpa's new phone background — “Pajama walk to grandpa's on Christmas morning. He took one look at the grump face, laughed until he cried, and made me send him the photo three times.” — Chris O.

      FAQs

      check_box

      What sizes does it come in?

      Sized by age in months, same as regular baby sleepers. If your little one is between sizes, go up. The fleece is roomy and it is nicer to grow into than out of by Christmas morning.

      check_box

      Is the hat separate?

      No. The hat is sewn onto the hood, and the hood is part of the onesie. One piece, one zip, nothing to lose under the tree.

      check_box

      Is it safe for a baby to sleep in?

      It is made for lounging, photos, and pajama mornings. For overnight sleep we suggest lighter sleepwear, and always follow your pediatrician's guidance.

      check_box

      How do I wash it?

      Machine wash cold on gentle, inside out, then air dry. Skip the dryer so the fleece stays fluffy and the face stays crisp.

      check_box

      Can older kids wear it?

      This one is cut for babies and young toddlers. If you want a bigger size, tell us in the reviews and we will bring it.
