In desperation, G-Ma came up with a stroke of genius. She had me set a ladder outside the nursury's window. Then she lay the boys down for a nap and went her merry way. I stood patiently on the ladder, peering over the edge of the window. You wouldn't believe what I saw that day!
The boy's were always too hyper to nap much. It wasn't long before Brother2 was pulling himself up by the rails to stand. Brother1 was awake, but just lay there quietly watching. Brother2 stood there for a minute, listening... looking. He must have decided the coast was clear. I had to stifle a gasp as I watched him pulled his torso up to flip over the side of the crib and execute a well-practiced landing on the floor. He paused there, listening... looking... before crawling over to Brother1's crib.
Brother1 was grinning from ear to ear with anticipation. Brother2 crawled over to his crib and kept going straight under it. He rolled over onto his back under the crib and proceed to kick up against the bottom of the crib. The springs under the mattress hooked into a couple of large eyehooks on the head and foot of the crib. Brother2 had figured out how to kick those springs right out of the eyehooks! Down came springs and mattress with Brother2 sliding right to the floor.
Once down, the Brothers proceeded to detach the mattress and springs completely and begin pushing the crib away from the wall. When there was enough space, they both crawled behind it and pulled into a standing position with the wall at their backs. This is the only time they made a sound. They looked at each other, leaned back against the wall, said their equivilent of "Go!", and plunged forward against the side of the crib. Their weight was enough to topple the frame into the floor with a crash. Mystery solved!
Did you know that chicken wire makes a right proper lid for a crib?
