Frequently Asked Questions
Does bamboo really help with eczema?
Yes. Bamboo fibers are incredibly smooth and round, which means they do not have the microscopic hooks that cotton or wool have. This reduces friction against the skin, helping to calm flare-ups.
Are the snaps nickel-free?
Absolutely. All our hardware is nickel-free and lead-free to help avoid skin irritation.
Will it shrink in the wash?
Our bamboo fabric is pre-washed to minimize shrinkage. Wash cold and tumble dry low to keep the tee soft and smooth.
Stays put through the crawl, the carry, and the high chair.
One piece = one less layer to fuss with at every change.
Bamboo so soft moms keep checking the label to make sure it is clean.
Cute enough for the playground. Practical enough for the floor.
Holds its shape through wash after wash - no pilling, no shrinking surprises.
Sized 3M-24M so you are not re-buying every six weeks.
The Science Behind the “Onesie Tee”
1
Snap-Tucked™ bottom
A soft underlayer that snaps clean below the diaper, so the tee can’t ride up.
2
Bamboo Fabric
Ultra-soft, breathable fabric that naturally regulates temperature and stretches with baby’s belly, hips, and rolls instead of fighting them.
3
Grow-with-Them Fit
Bamboo fabric’s stretch and recovery means each size lasts longer than a typical cotton tee.
4
Gentle on Skin
Naturally smooth and hypoallergenic, ideal for sensitive baby skin.

These shirts are perfect! The quality is impeccable, to the point where I don’t want the boys the ruin them!! They are so soft, nicely made, and clean up very well. Thank you for distributing a quality product! Also, they have room to grow into them which makes me happy as they will be able to wear them for longer! The twins approve!
We love this set! The material is thick but soft and stretchy. My son is big for his age, at 14mo he's 33in and almost 30lb. The 18-24m set just fits. I wish I would've found these clothes when he was younger!
Cannot rave about these enough! We want every single shirt offered. We live in these, and now I don’t want to put anything else on my little one. It’s so soft and stretchy. True to size and stays down. Love love love!
I have the driftwood. Now I need the dusty blue. These shirts are the best of the best! So soft, bamboo cooling material, stretchy so little one can wear for a long time. It’s worth the investment! I recommend to everyone I know!
Store owner replied:
Ahh yes!! Driftwood + dusty blue = total dream combo. So glad you’re loving them — the bamboo, the stretch, all of it! Thanks for recommending us to everyone, we appreciate it so much!
We LOVE these shirts! I recommend them to everyone I know. No worries about them riding up! We live in these shirts. The bamboo is cool making the two layers perfect! I have the blue and mauve of this one. You need them!
Store owner replied:
Yay! We’re so happy you love it! We totally get it—onesies and pants don’t always work well together, which is exactly why we created this set. So glad you’re loving the softness and ease too! Thank you for your support!
The absolute softest clothing- great fit. My kid loves wearing this set. He always gets a lot of compliments when he’s in it. Don’t hesitate to buy this- you’ll find yourself reaching for it constantly.
Store owner replied:
This is the best thing to hear! Comfort is everything for little ones, and we love that your kiddo enjoys wearing it (and getting compliments—so fun!). Thank you for your kind words and for being part of the Black Sheep Baby Co. family!
This tiny pocket is the sweetest and I love that it comes in one of my favorite neutral colors.
I can’t wait to gift these to my grandson. I know my daughter-in-law is going to love putting him in these. They appear so comfortable and they are very soft.
