His dexterity is improving every day but it's still pretty tricky for a 6.5 month old to actually pick something up intentionally, and letting go is just achieved by a little arm flailing until the object falls away.
So this game would give him lots of opportunity to practice picking an object up and then putting it down (or dropping it) back in the box or on the floor - because with so many eggs to choose from I thought he would be eager to hold lots of them.
But he just wanted to look at them...but Freddy wanted to touch...
And when Freddy couldn't resist the lure of the eggs Henry made him wait a little longer, as if something was about to happen.
Then, when the time was just right (and his big brother had got bored and moved onto something else) he started to rummage around slowly and methodically until he had chosen the egg he wanted to remove.
