Ok, so I've got 2 DDs who both have birthdays coming up in the next few weeks (their 7th & 10th). They already have all of the 'big' presents they need (eg bikes, trampoline, swing set etc) and more toys and games than they can possibly play with (we have quite a big family so get quite a lot of stuff from the GPs, Aunts & Uncles etc).
All of the family members who buy them presents always ask us what to get for them and this year I've just no idea what to tell them. I've been poring through the Argos & Smyths catalogues looking for ideas and the thought of just buying more stuff that they don't need or have time to play with (they've still got stuff from Xmas that they haven't got out of their boxes yet) just makes me feel sick. It's just so wasteful. And this is all before we've bought them anything 
I did think about asking for money but tbh just getting money when you're 7 (or 10) is a bit shit (also the family members like to buy them something to see them unwrap it). Having a birthday with nothing to unwrap would be shit.
I'm really at a loss for what to get them this year. Has anyone got any ideas for presents for a 7yo & 10yo...?
