Black and White Dotted Cart Cover For Twins
I love this twin-friendly cart cover ($50) from Etsy user Practical Designs. If you have twins, or know someone with twins, this cover easily fits massive carts (think Costco or other big box stores). And even if you don't have twins, you could easily use this cover for your kids if they are close in age.
Each cover comes with two pillows and two adjustable locking belts, so you can rest assured your toddlers stay safe and secure inside.
