## Description

This is the first tummy time product that actually 'tells mom how to!". It provides instructions to caregivers of how to do tummy time From birth to six months. This versatile mat features two flexible arches that start as a border around the mat for tummy time play and then stretch over baby with dangling toys, encouraging your curious little one to reach and play. The toys detach so you can bring them with in the car seat or stroller for more playtime on the go.

Review: Beautiful - It’s beautiful. I went with this one instead of the more spendy lovevery one I had my eye on. It’s maybe a little smaller but it’s super cute, has many lovely toys and similar color scheme as lovevery and not overly stimulating like some other loud and obnoxious play gyms on the market! I got it half off with open box, I figured if it was messed up I could return it and buy new however it arrived with a little bang up box but was totally perfect and like new inside. It arrived with all the toys and even the sticker to protect the mirror is still on. Very very happy with this purchase and the money I saved. I will add a little pull toy from taf toys that has a color changing light and plays some soothing sounds, add some more toys and contrast flash cards… very happy with this purchase.
Review: Great - Excellent functionality for early STEM skills, with vibrant colors that hold little ones’ attention. Great value for money — sturdy and durable, surviving lots of play without wear. Assembly is super easy, and the pieces have no scent, just a clean, safe feel perfect for babies.

## Questions & Answers

**Q: Is it reversible?**
A: This one is not reversible, just a soft white fabric on the back, but for an extra $10 the one at Buy Buy Baby is and has the months printed on the back for photos.

**Q: How do you get the arches up and crossed? I think I may be missing the piece that attaches them!**
A: There should be a strap in the middle of one of the arches that can be used to wrap the arches together. If not, please contact us at allaboutsassy@sassybaby.com!

**Q: How do you get the arches to form a circular border?**
A: Thanks for reaching out! You can remove the arches from arch position, and place the two poles on the ground. Connect the buckles together on both ends of the poles. Secure one pole in the velcro insert on the mat, and secure the other pole on the other side into the velcro insert. This will form a circular shape around the mat to attach toys to. Enjoy!

**Q: Does it fold/is it portable?**
A: Yes, it folds and it is portable. It’s a beautiful playmat!

### ⭐⭐⭐⭐⭐ The only baby gum and toy you need! So good I had to write a review!
*by K***E on March 24, 2021*

I love how this is designed! This is our second babe and I felt a little silly buying a new play gym but our old one was too busy and not very engaging. My two month old LOVES - literally loves - this play mat! There is a gentle jingle toy, a mirror, and high contrast toys without being overly stimulating. My favorite part is the design. You can Velcro the various toys wherever you want and adjust them super easily. There are a few that stay on the arch but can be removed if you unclip the arch and slide them off. I also love that you can lower the arch so nothing is above their heads if it’s getting too busy. It’s super cute and really developmentally appropriate. There’s tactile toys and visually appealing toys. I love the rainbow pillow for tummy time. I never write reviews but I always read them when making a purchase, especially for baby things. This was good enough for me to write the review lol. Everything the company thought of for this play mat is intentional and designed with parents and babies in mind!
