My son takes naps during the day with my wife, while our niece whom she watches, sleeps in his crib. Our problem is that when he sleeps in our bed for his nap, he has a tendency to fall out of bed, sometimes even knocking his head on the nightstand on the way down.
We’ve tried everything: pillows, blankets; all piled up next to him, but he is such a toss-n-turner that he works his way right over them and onto the floor. They have bed guards at Wal-Mart, Costco, etc, but they all require a permanent anchor, and since I sleep in this bed at night, I don’t want to have to deal with it.
I came up with the following idea, and it’s far safer and durable than store-bought methods, and it’s simple, effective and cheap. It cost me about $29.00 to put this together and about 4 hours of my time.
It’s basically a PVC construction that slips between the box-spring and mattress on one side of the bed when my son is napping, and I can remove it when I go to bed at night. When not in use, it sits up against the wall and holds my wife’s arsenal of pillows that she keeps on the bed. We’ve found it can also be used on a couch to keep small babies from rolling off if you don’t have a Boppy pillow handy. What’s also nice is that I can expand upon it when my son goes into a big-boy bed. I’ll just remove the bottom segments and extend them across the bed to another guard for the opposite side. Mulitpurpose!
UPDATE: I've updated this Instructable due to some comments from concerned members. I've made two options: Option A (the original Instructable), which is for larger kids, with larger heads (like mine), and Option B (a new modified model and cutting diagram), for infants, babies and small toddlers.
