Crossbody Diaper Bags, small diaper bags

I absolutely love it! I’m not a bulky purse person, (for reference the black purse is my everyday go-to) My City Mouse diaper bag is exactly what I was looking for, it has just the right compartments for the essentials, and it’s compact yet super efficient.

I love this bag SO SO SO SO SO much. It's a great diaper bag and just general purse. It's cute AND fits a ton. It shipped so quickly and the quality is awesome. 10/10 would buy again!

You can’t get a better combo. I’m legit looking at buying it for my cousin who is TTC. The quality, the packaging the design and compartments/organization. The reviews didn’t even do it justice. Add a paci pouch!
