"Camping holidays by public transport are a fraction of the cost of travelling abroad, it can be expensive, but it can be very cheap too, cooking has to be done anyway, singing is free, voluntary work is free, days out can be free, lots of sport is very cheap, swimming is the only thing I mentioned which is costly
Conversation is free, reading together is free, growing a few things in a pot is very cheap."
I spent loads of time doing all the free and cheap stuff mentioned with dc and encourage my dc to do voluntary work and sign up for ambassador activities at school.
You pass on your own passions. I love going out, nature, astronomy, science and geography so I spent lots of time talking to my dc about these things and doing activities.
It didn't cost anything to look at the stars, watch the International Space Station go by, watch a launch on tv, find countries on the globe, discover local wildlife, feed the birds and identify them and so on.
It's all about engagement and work ethic.
