why would someone go with an 8 year old to the loo? in familiar (I assume) surroundings, where she is almost certainly known?
my dd1 is nearly 8. she is just begining to go to the loo independently if we are in a familiar place - she wants to go independently far more often than I let her. (dd1 has severe ASD before anyone thinks I am a hovering overprotective sort). I have my 5 year old dd2 telling me 'it's ok mummy, I can go as well, and we'll be ok'
seriously, you think an 8 year old NT child should always be accompanied to the loo?
dh and I have had our moments when out and about with the dds - and we are, most of the time, almost surgically attached to dd1 due to her disability. we are trying very hard to come up with ways to help her be independent (as she wants to be) but failing so far. and yet we have still had our moments of panic and 'where's dd1/dd2'. thankfully neither have been actually lost thus far, but I can easily see a time when they might be.
as other posters have said, it can be so easily done, especially once the children are at the 'I'll jsut go and find mummy/daddy and ask them about it' stage - dd2 is particularly adamant that she will be fine wandering about and 'finding' the other parent in eg B&Q or IKEA
