I absolutely love our ERGObaby Carrier, I don't know how I would survive the early parenting years without it! So glad I bought it when we had our first baby, even though it was pricey for us. It does get a ton of use though and now that Baby T is teething, he is putting it through a rigorous test by constantly gnawing on the shoulder straps. So I decided that the Organic Teething Pads from ERGO would be perfect to protect the straps and not have to wash it so much, not to mention that I would rather him be chewing on organic cotton than the strap material (whatever it is made of).
That photo is pretty much Baby T at all times when he is in the carrier, I don't remember when was the last time he was in it without chewing on the teething pads. He falls asleep right after chewing for several minutes - that's the day we went to a farm with animals, it was nice to have my hands free to take photos, play with my toddler, and hold a water bottle. It seems that chewing is very therapeutic for a teething 7 month old, as if that's what puts him to sleep right away. If your baby is not at the teething stage yet, trust me - you'll wish you had these once the baby starts destroying those straps!
The pads are very easy to use, you just snap them on with little snaps (like the ones on clothing, not cloth diapers). They come in Mocha and Natural, I have the Mocha ones - it's a neutral color that pretty much will look good on any carrier. I also think these would be great on car seat straps if you have an issue with your infant chewing on them, though they may be a little shorter than typical car seat strap covers. They are reversible, though I only use them on one side. I have only washed them once so far, just threw them in a cold wash with gentle detergent and a delicate drying cycle. They came out slightly wrinkly and a tad smaller than they were, I think - maybe that was just the impression I got (not like I measured them!). They would be very easy to hand wash too, a lot easier than spot washing the carrier after your baby chews on it.
The ERGO Organic Teething Pads are only $20 for a pair, which I think is a great price considering how much you pay for the carrier. I'll tell you it is so much easier to throw the pads in the wash than the whole carrier! Obviously you can't wash the carrier after every time the baby chews on the straps - that's the problem I ran into before. He would chew on it and spit up right on the strap area, spot washing it was hard and not productive. Now it is so much easier to just throw the pads in the wash and the whole carrier is kept clean. Unless of course you get a poop explosion - thankfully that doesn't happen much with cloth diapers!
