Just make sure you know what's on film lol.
In USAistan, a grandmother was locked up for kiddie porn for having pics developed that were of her toddler grandkids in the bath.
I once found an old exposed film cartridge, and it dated back to when kids were younger, but I was afraid to get it developed as one of my boys went through a phase around age 8 with a kiddie camera he got as a gift where he was taking butt shots thinking it was hysterical so we had to take his camera away. I fear what if he got his hands on the main camera?...hence left the film alone.
