There is a common belief that you should pull on the straps of your carrier to test it’s durability and security before placing babe in the carrier. This test is referred to as the “tug test”, and has been debunked by babywearers and manufacturers everywhere. The test actually puts stress on the carrier’s seams in ways that wearing a baby never would, and therefore can actually cause more damage to the carrier than using it would, ultimately making it potentially unsafe for babe (if you have damaged the carrier). For this reason, we recommend not doing the tug test on your carriers.
The Baby Carrier Industry Alliance (BCIA) wrote up a great article on why you shouldn’t tug test and what you can do to make sure your carrier is secure, please check it out here.
