When I bought these I never had a photo shoot with the kids in mind.  But I must say when our little girl climbed in one in the playroom to play it was perfect.  All I had to do was go find the other one and I had a container for the kids.  Which means they stayed relatively STILL.  Can I tell you how odd that is?    They were so still (well, relatively speaking of course) that I managed to get a few good pictures.

But alas even in a container they move...

He did get in and out a few times

It was quite the game.  Then she stuck her feet out a couple different ways

and fun was had by all!  I must say I enjoyed one of the easiest times I've had lately trying to catch them for a good picture, so even I was happy.

So all in all these are the perfect container.
