This is by far one of the best creations ever. It's my cheat, as a mom of twins...especially with my 21 month old Mattootles running around. ;)
It is a bottle prop. (Or as we call them "bottle proppers" because they are proppers of bottles). Click here to read more about them or if you need one. Who says mom's of singletons can't use them too?
Here are my little monkeys using theirs. Marco is a pro at holding on like he is riding a roller coaster and Massimo is more of a daredevil with his hands above his head.
They work really well and are machine washable (so they say, I am doing that today so I will let you know how that works out for me). You can't just prop them and run away, you have to keep an eye on them (of course) but it's not eyes that I'm short on, it is hands I need more of.
