So, I have DDs aged 10 & 12. We have a close neighbour with a 2 yo and 4 yo who my kids adore. Now that they can't play together, we have been sending them daily video challenges and we are soon going to run out of ideas so I thought I would ask the MN hive mind. So far we have done:
Find as many books as you can with pigs in
Find 5 yellow toys and order them biggest to smallest
Make a smiley face out of things you find in the garden
Find as many hats as you can and put them on your head
Dress in all the colours of the rainbow
My mum has also been forwarding them to a couple of friends of hers with young kids who are also joining in and so we are feeling the pressure! 
Any ideas? TIA
