Engagement in the news and current affairs from a young age. My parents listened to me stand on a chair and announce my plans to ‘solve’ domestic and international issues, then asking questions posing as various journalists and MPs. Writing letters to politicians and creating presentations for pet/toy requests. Loved the Working Lunch and mum would pick me up early so I could get home in time to watch it.
20 questions general knowledge quiz every night written by my dad.
Thousands of books in our house, including shelves of my own in my bedroom - I read at least one book every day from about 4 up.
Every question I ever had got answered (and I had a lot of them) - even if it meant letters to universities or a trip to meet a chemist once at the Science Museum.
Toys for me were more creative and role play based, or exploratory. Kids learning laptop, a microchip board from a business throwing it out, doctor set with book detailing illnesses and treatments, a whiteboard for my teddy bear school.
Every time we went out, my dad played the game of “if I ordered x, y and .; how much would that be?” “If I put with a £20, what change do I need and what denominations could that be?”
Holidays and days out weren’t ever spent at the beach or pool. We would go into the city with a phrase book and explore the history and culture.
Always facing the world as a baby. High chair facing the garden to observe the squirrels, pushchair facing outward. Allowed to engage with the world too, I always had a side business going on. Sitting in our front garden selling water to runners, selling seeds I found to gardeners, eventually led to website based ventures when I worked out how to ‘borrow’ other people’s internet.
Strategic conversations: “if this, then what?” Like on coin machines, long discussions on timing and the optimum coin spread. I was a very exciting 4 year old as you can imagine 
The thing is, I loved these things. If I hadn’t, it would have backfired - and that’s probably nature. Being an only child helped, given how time intensive this all was on my parents.
