This baby cot was first used to "cage" baby, especially when I needed to cook and stuff. But then, he started to climb over the raised railing and that got dangerous coz' he would fall over head first. So I lowered the railing and the big kids started to have fun with it.
Well, if you ever need to keep your kids busy, give them some blankets and have them make a tent. I'm sure you've done this sort of thing when you were younger. I know I have. There's just something intriguing about crawling into covered spaces.
So, if you can't camp outside, just camp inside first.
