I'm not sure my baby prefers pink over blue, but he loves Angelina Ballerina and Bratz and a bunch of other girly cartoons, so he got the pink version.Anyway, so far my 2.5yo baby boy has been pointing at the circles and points and lines and saying "circle", "point", "line", or one of the various colors. I don't think he's really 'getting' any of the geometry yet (Euclidean or non), but he's having fun. And that was the point of the book, right? It has some fun word play "Angle one is a cute little angle" and "Those four angles look all right to me" that is lost on little kids but makes me smile every single time I read it to my son.My only problem with the book is that it's a roughly 8.5" by 8.5" paperback, which makes it pretty vulnerable near babies/toddlers. It really would be better if it were a boardbook. Then I'd be able to leave it out for the kids to look at themselves whenever they feel like it, and I wouldn't have to keep reminding my son to be gentle with it while I'm reading it to him. ### ⭐⭐⭐ Definitely for babies with upper middle class or wealthy parents *by A***S on Reviewed in the United States on October 16, 2016* I own several of the Math for Babies series of books. While I really like the calculus one for example, this non-Euclidean geometry one is both shorter and with less interesting pictures. While it does give a baby explanation of Euclid's fifth postulate and it does show how initially parallel lines on a manifold can cross, it does not explain (in baby terms) some of the other simple ideas behind non-Euclidean geometry. So, in comparison to some of the other Math for Babies books, I feel like this one is a bit weaker. Combine that with the fact that the price is $11 and I feel the publisher is asking too much. This "book" is really more of a pamphlet and should cost about $3. You will have to decide if it is worth the price. For my wife and I (I am an engineer and she is a mathematician), we felt like this book was a bit too small and over priced for the quality of information within (which we could have taught our son for free). Three stars for this particular work. ### ⭐⭐⭐⭐ Perhaps better for adults than children *by B***Y on Reviewed in the United States on January 31, 2016* I'll be honest, the book is called "Non-Euclidean Geometry for Babies" but I'm a 27-year-old attorney and I did not know about Non-Euclidean Geometry prior to this book. I learned a thing or two about semi-advanced mathematics. The language was simple enough for children to understand, though I'm not sure that the five-year-old child with whom I was reading this book fully grasped all the concepts. Still, it was a good way to introduce complex thought to young children, so that when they come across these concepts later in life they're not totally taken by surprise. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/3793584-non-euclidean-geometry-for-babies-math-for-babies](https://www.desertcart.pt/products/3793584-non-euclidean-geometry-for-babies-math-for-babies) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
