For some reason, we just weren't willing to invest in one of those shopping cart covers, even though we usually wipe down our cart with a disinfectant. An even better solution: this shopping cart cover made out of: a pool noodle! That's right, it's just a pool noodle cut in half (so you actually will get two covers out of one noodle) and cut down the middle. It slips right over the shopping cart so baby can't gnaw on the metal bar. Now's a great time to pick up one of these noodles.
