I feel it's very important to point out that there are other, excellent child minders available, and those excellent childminders definitely DO take the children to Chester Zoo.
And....(drumroll), I have evidence!!! Dah dah daaaaaaah!!!
Many thanks to the excellent Childminder who found my DS in Chester zoo when he got lost there two years ago.
Near the butterfly house if anyone wants to own up to being that excellent child minder!
DS was 3 and out for A Big Treat while staying up north with proud grand parents...
They had the whole zoo on lock down and my parents were completely freaking out that they'd lost their beloved grand son and would have to tell me what they'd done! I don't know how long it took to find him, my parents varied between just a second, and, forever and ever... So somewhere in between I guess. Those minutes of panic are loooong and I'm so glad I didn't know until it was all ok.
DS didn't actually realize he'd been lost until some time afterwards (silly sausage). From his perspective he'd told his granny he needed the toilet twice and she 'ignored' him, err, didn't hear, Granny is going a bit deaf DS!
Anyway, DS thought she must be Really Interested in the tank she was looking in so decided not to bother anyone as he'd noticed a loo sometime earlier. So just trundled off and navigated his way quite some way to the loo, managed all the doors, sink etc, and it was only coming out of the toilets he got turned around and set off happily in the opposite direction... Just as it dawned on him that he'd been walking a long time, and his granny and grandpa were still not there, a lovely Childminder zoomed her buggy over to him and asked if he needed a hand, reassured him, grabbed a zoo employee who radioed to get the poor gibbering mess of my parents, while she stayed put with DS (as DS wasn't sure about going off with a 'stranger').
DS said she was very kind and they were going to have a picnic, & he'd wanted to join in. My mother said the child minder was wonderful and calmed her down, which would have been a major achievement tbh! The Childminder said seen him a bit before and was keeping an eye on him ... he must have looked very purposeful as no one seemed to notice the lone explorer on his travels until her!
DS steadfastly refused to believe he was lost for a long time after, and got quite cross at me, saying he couldn't have been lost as he didn't feel lost, but granny and grampa got lost and were naughty wondering off until the lovely Childminder helped him find them again 
So there, a definite sighting of a lovely childminder at Chester Zoo. Thank you!
