The only school available was Catholic, and there is no such thing as a secular school.
Dd1 was getting more and more stressed. She struggles with social situations, but has become so much more confident now she can have shorter bursts in smaller groups. The change is amazing. She is 5.
Dd1 is learning about Ancient Eygpt, to play keyboard and cornet, to cook, to tell the time, to recite poetry, to write poetry, grammar, a different culture or festival every week (with appropriate trips, food, music, art, talking to people, etc), she learns art in a free class at a university (Russell Group, if that helps...), we go to at least one museum, usually two or three, a week, where we get to look and and use whatever we like without queues and/or play with our HE friends and ask questions of the experts.
She knows how to buy a bus ticket, add up the price of simple shopping and make choices to stay in budget, return and self issue library books, cook simple meals with minimal supervision, find and identify minibeasts, ask directions in a supermarket, use google, use an encyclopaedia or dictionary, use a microscope, use a map.
She had one of her school friends around for tea last night and is going to another school birthday party on Sunday. She also does dancing, rainbows and plays in the street (when it isn't flooded...) with general local children.
In the next few weeks, we will be going with HE groups to hear the nativity story in a 900 year old cathedral, have a tour of a fire station, have a tour and activity session in a modern art museum, to a planetarium, to a science show, to a soft play centre and to a wetlands centre. Plus of course the more spontaneous meetups.
My nana needs care, and so we travel over to give my mum a break, and while we are there we meet up with friends, go to the seaside, see different museums, talk to nana about her life, learn to knit and sew, make inventions, fly kites.
We can go and visit my (teacher) sister in London, or my student sister in Sheffield. We can get cheap trains to Scotland. We can go on political demos. We can go camping at cheaper times.
No matter how good the school, it would struggle to provide all that, and poor dd was too tired after school.
