We estimate that you will be able to put your child to sleep until he is approximately 4 years old: The first times you will need to use NAOS closed to keep him safe. Then thanks to its opening on the side you will extend its use beyond the acquisition of mobility.

We can even imagine using NAOS beyond the age of 4: the cabin roof will make it its playmate even far beyond!

There is no child weight limit for using NAOS. On the other hand, it is recommended to no longer use it in the closed position when the child begins to want to step over it, to limit the risk of accident. It will then be time to use it in the open position.
