How to measure
- Length: from the top of the shoulder to the bottom of the leg
- Sleeve: from the shoulder seam to the cuff
- Chest: straight across the garment, just below the underarms
- Shoulder: from one shoulder seam to the other
Sizing tip: Between two sizes? Go up. Babies grow fast, and a little extra room keeps the sleeper comfy all winter.
Spikes all the way down.
Soft spikes run up over the hood and down the back, so it reads as a dinosaur from every angle — including the one you'll actually be photographing: the back of them crawling away from you.
Softer than it looks.
Brushed flannel fleece, warm without being stiff or scratchy. It's the difference between a baby who settles into a costume and one who spends the evening trying to get out of it.
One zip, done
It opens all the way down, so getting them in takes one pull rather than a wrestling match.
And changing them doesn't mean undressing them completely on somebody else's sofa.
FAQs
DinoBoo Q&A
What size should I pick?
Go by your baby's age first, checking their build. Between two sizes, always take the bigger one.
Is it too warm for indoors?
This is a thick flannel built mainly for cool nights. In a warm room, a simple onesie underneath is plenty.
How do I wash it?
Cold gentle cycle, tumble dry low or hang to dry.
Free Shipping?
Yep! We offer FREE U.S. shipping as well as FREE shipping to 20+ countries worldwide.
What is the duration of the warranty?
All our products are covered by a 14-day warranty from the date of receipt, for your peace of mind.

22 hours agoMMarta S.Verified BuyerHighly recommended!Excellent quality flannel, much thicker than I expected for the price. The zipper runs smoothly and doesn't catch on the fabric, which was a huge plus during late-night changes. Highly recommend.DinoBoo Dinosaur Print Flannel Baby Blanket Sleeper Was this helpful? 0 0
