For me, I don't think I would let them go in on their own, I would want to take them with me. It’s usually when they are a bit older -around 7 or 8 – that they want to go in alone.
As a single mom I would never send my 6 yr old boy alone into a mens bathroom. This world is full of sickos and to go through life thinking it'll never happen to me is beyond naive.
What if the child has got a disability or a mental age of two or needs assistance?
