a carton of eggs
a stuffed animal
sit your child in the living room and scatter eggs aroud the room and say “you have crawl around to find the sofa without breaking an egg”, now blindfold and spin your child around. Say “Now I’m going to move the eggs so you can’t use your memory” pick up all the eggs. Now give your child their soft toy and say “now you must be very careful not to get egg on teddy”. Now watch your child crawl through avoiding the eggs which aren’t there.
To make it harder cover them with a big blanket
Don’t try this with little ones that fret one you try to wash their soft toys.
