Three things.

Does anyone know where I could get a surgical mask for all ages?

An astronaut helmet for children, preferably as an accessory.

A mod that allows sims to nap on their beds. (if it's possible)

I haven't been able to find one for all ages, but here's a mask for adults and elders: http://www.modthesims.info/download.php?t=128828

I converted that mask for all ages, for my own use. Boblishman apparently does not want his stuff fiddled with ("Do not clone").

(In fact, I did not "really" clone it. I've had troubles with that mask showing up wrong (Like the mesh is turned inside out), so I had to clone another mesh without that problem, and put the old and new meshes plus the texture inside that package. Only thing that helped...)

Ah I see. Thank you for your help. (:
