Picture of How to make a Toddler Bed Guard
Our predicament:

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. 

DISCLAIMER: Please keep in mind that this is my method is what I have chosen for my family. I’ve done a lot of work in the past with PVC and have a lot of experience with it. If you aren’t happy with what I’ve put together, don’t make one for your kids. Go out and buy your solution. Remember, I am not legally responsible for what you do with this Instructable.  Just keep your kid from falling off the bed!

Your distance between slats is way too big.  The "code" says it needs to be smaller.  I cannot remember the number, but I think it needs to be under 3 or 4 inches.  With the distance you are using the toddler can stick his/her head between the slats, get trapped and perhaps even choke to death.

I've updated the Instructable to show two options for making the toddler guard:  Option A (the original) and Option B (a modified version).  Option B keeps the rungs less than 3 inches apart, and only adds the cost of about 8 more Tee fittings.

Hope you approve of the update!  Let me know your thoughts.

You make a completely valid point. 

The purpose of my creation is to keep my son from falling off the bed and hitting his head on the floor and the end table.  I certainly didnt intend to replace one harm with another, however, my son is three and has my 'prominently sized' head, which does not fit through, so for my case, I am fine.  I will update the instructable to create an option where the user can put the PVC fittings end-to-end, which would leave a 3" gap.

I do suggest that the end of the instructables that "Another optional item would be to put a mesh-netting over the whole thing for very small children, such as infants".   I'll press this one on too.

If there's any chance at all that your toddler might be chewing on this thing (which I would think there is....) you might want to reconsider your materials  PVC is nasty stuff..not "food grade" by a long shot.

No.  Mine is past the chewing phase.  However, PVC at room temperature is fine.  It's when it gets heated that it can become dangerous.  That actually goes for any vinyl-based plastic, which, sadly, is what most toys are made out of.  The pipe I use and the fittings that I order from Formufit are made in the US and contain no leads, like some foreign PVCs do.

Still a very good idea. Well done.

 PVC's a miracle, isn't it? Great idea, I could have used one of these when I was little; I was always falling out of bed too.
