Our Milestone Number T-Shirts are the perfect celebration for your child's birthday. They'll wear it with pride all year long!
Whistle & Flute clothes are designed to be playful, unisex and cool. We want your kids to be comfortable at all times so we use the softest fabrics and all safest inks. We focus on quality so they can be worn for years to come.
Fabric & Care
100% organic cotton
We know the last thing you want to do as parents are to have kids clothes you need to fuss about. We suggest throwing it in with everything else on cold and tumble dry low.
Fit & Sizing
Please make sure you select the correct size for the number shirt you wish to order.
We find our T-shirts to fit true to size. size 1-2 fits like a size 2T, 3-4 fits like a 4T, 5-6 fits like a 6T and so on. If you want to be doubly sure, take a couple quick measurements of one of your kids current shirts to compare to ours. Measure under arms around the widest part of the chest. Length measures from collar to front hem. Please email us if you still have any questions!
My son loved having this shirt for his 4th birthday and so cute.. Thankfully it’s available in 5/6 but it’s a smaller fit than most T-shirts in that size.

Fun shirts to buy every year. We’ve been buying them since our little guy turned one, and just bought the ‘5’ shirt. I think we’ll likely stop at this one. :)
Claudia F.
With our son being a leapyear baby! This one was a special one!
His actual bday was ON THIS YEAR:) when he turned 8 or technically “2”
He’s had these milestones T-shirt’s for years and the quality of them has remained amazingly soft, and durable. We live everything Whistle and Flute!
Clemence T.
So nice. Good quality, week made.

We love our 4 t-shirt. Definitely making this a tradition. Gotta grab a 2 for the littlest next.
Jennifer Y.
sad that 7 is the last one! Can we extend up to 10?
Julie D.
I was pleased with how quickly I received the t-shirt. I also think it's great quality and a nice soft cotton .
Julie-Ann Wern-Yar L.
Love how my daughter can wear it longer and not just on her birthday. Love the feel of the fabric its very breathable
Caroline L.
Tellement magnifique ❤️
Amanda C.
I love this shirt. The quality is great and it’s well made. My only complaint is that it doesn’t come in a smaller size and I have a petite 2 year old so the 1-2 years is big on her.
Irene L.
This was an adorable way to commemorate our child turning 2! People loved the shirt.
Eli N.

We love the number shirts and have made it a tradition every year to wear for my sons birthday. Quality is amazing and shipping was fast. Thank you for making a great product and can pass on.
Lauren M.
I love the shirt and the beautiful design. We have been buying them since my sons first birthday, but this years shirt runs very big compared to the previous years. All the other ages seem to have a choice in which size but sadly age 5 does not.
Becky L.
My son loves his number shirt!! It’s long on the torso and is so comfy!
Eunice G.
We absolutely love our number shirts! We’ve been buying them since he turned one and I have been pleased since day one! There’s no cuter design out there!

Great quality and soft! Fit true to size/age for my son

Last year I forgot to buy my son's birthday shirt and ended up having to purchase a crappy one on Amazon that was at least two sizes too big and on a really thick, stiff t-shirt. Not this year! This year I planned (way, way) ahead and got this shirt for my son's birthday, although I know he'll love wearing anything with "his" number on it throughout the year, which is why I'm happy to buy a shirt from W&F, because I know it will stand up to many wears and washes and dries and will still be able to be passed to little brother. I love the softness of this tee, the fit is great, and the graphic is simple and cute.
Tracy T.
Great quality. Fit is on narrow side. Awesome birthday shirt
Kristina B.
I ordered the No.3 in size 3/4 (only option at the time). I find these fit a bit more on the small end. My son can wear a 3 or 4 in Old Navy and Gap and this shirt fits more like a 3. Love them regardless; we've been doing them since age 1 and will pass them on to my daughter!
Kate K.
We haven’t worn the 3 yet but for 1 & 2 we adored the t-shirts. Cute tradition and ultra soft material!
Fela C.
Every year we purchase a new milestone shirt for our son. It is a birthday tradition. I love seeing photos throughout the year with him wearing his number shirt. I hope that there will be more numbers, since we just purchased the “6”. Thanks Whistle and Flute for the beautiful designs.
Patricia D.
Perfect tee for my almost 3 year old, we have them for every year!
Kim P.
Jen H.
Bought the shirt a little large so my babe could wear it for awhile. This shirt is a nice weight, not too thick or thin, and wonderfully soft!

My son has been wearing his W and F number shirts since his first birthday ! They are a staple birthday outfit for him and we pass them on down to younger cousins too!
Caroline J.
Fab t shirt! Looks wonderful and great quality.

I love these t shirts. I bought 2 and 3 for my son and just bought 1 for my daughter (I hadn’t discovered them yet when he turned 1!). Lots of compliments from them and they are perfect for the big day!! They look fab on photos too. Excellent quality.

Mary Ann G.
These number tees are a great source of pride for my granddaughter! Wearing "5," she reminded me recently that she's about to turn 6 and will need a new tee. Number "6" awaits the big day. The quality of this tee is great! Washing after washing it still looks like new. Thank you Whistle & Flute!
Kristie J.
Im super impressed with the quality and feel of these shirts. I will buy them again!!

The #4 shirt is a size 3-4 which is the same as the #3 shirt. Unfortunately this means it’s too short and tight for my soon to be four year old.
Sarah H.
The perfect shirt for my soon-to-be one year old!
Daisy D.
I love this shirt! It was perfect for my sons birthday and the quality is amazing!
Natalie B.
There were some lose threads in a couple places (shoulder And bottom) with a trim it was perfect

the tee fits perfect right now, but think it’ll be small in a month or so, would’ve liked for him to wear it the rest of his first year of life. thank you!

Lindsay T.
I’m was so happy to snag this 6 shirt for my 2012 baby who turns six in June!! We have the whole set and we have passed shirts 1,2 and 3 through two girls so far and they still look amazing. Their new number shirt is the highlight of their birthday and they wear it on repeat all year long!

This is the third shirt I have bought and I love it! Itג€™s so soft.
devin d.
I love these shirts, but unfortunately we had a seam come apart which created a hole in the shoulder. Super bummed.
Becky B.
Your clothing is especially soft and my family loves wearing them! Everything weג€™ve purchased has stood the test of a very active little boy! Thank you for such unique, creative designs. We are customers forever!
Shannon K.
My oldest is turning six and we found these for his third burthday!!! My youngest now has 1 and waiting in his drawer for him is two! So we have them all! Sizing is spot on. Shirt quality is awesome, nice and soft. Highly recommend!!
Jessie E.
Always love WF! We have quite a few of their shirts (and outgrew our fav harems) and always get the milestone number shirts for my son, this is 3 going strong! Their stuff is great quality and cute, and my son and daughter can both wear!

I just bought this for my sonג€™s birthday... havenג€™t used it yet but Iג€™m hoping he doesnג€™t grow much before his first birthday. I feel the shirt is amazing quality and design but I donג€™t like the sizing. It seems VERY small and it would be nice to have the option to order one in a different size, as all babies are different in size. My son isnג€™t even large.
