Re: Carseats and oxygen levels, a question!
There are these as well, if your DS ends up having serious issues in the car seat. These have been tested my M'Liss Stelzer in terms of preventing desats, and I do know someone who used them with success. I cannot speak to their safety in use in a car seat though.
