Save yourself the drama and put one in your car seat even while they are in nappies! Car seat parts are so much more expensive than one of these beauties!
I’ve had this on my son’s car seat since he started toilet training. It has been great peace of mind knowing that if he had an accident it would be an easy clean up. If I had known about it earlier I would have had it on his car seat from the start. Great product, highly recommend.
