As these books tend to be short on footnotes, I couldn’t actually track down any such study. And what a study it would have to be: large-scale, “longitudinal,” intensely observational, randomized. Otherwise, how would we really know how much time children had spent in playpens (self-reports tend to be biased), what sort of households the children lived in, not to mention what might have occurred in the years between the time spent in playpens and the time of the reading and writing tests at age 7 or 8? Which left me wondering: Is the fear of playpens all hype? Just a hysterical outcropping of our anxious style of modern parenting?
Be sure to check the floor pad. It should also be no more than 1-inch thick, snug-fitting, and firm enough to protect your baby from falling or rolling into the loose mesh pocket that can form between the edge of the floor panel and side of the play yard (a suffocation hazard). We think it's safer when models have slots on the floor that allow the mattress's Velcro strips to be inserted and secured on the outside of the play yard, making it difficult for a baby or toddler to lift the mattress and possibly become trapped under it. Avoid models with a mattress that fastens to the bottom of a play yard only with Velcro pads that a child can access from the inside. Use only the mattress or pad that comes with your play yard.
The pieces were super easy to assemble. Just slide the rods on one piece into the holes on the next piece to connect them. I was a little disappointed that the rods/holes were not hexagonal like the instructions state. That would have locked them into position either straight or at an angle. Instead, the rods/holes are round, so the panels move around (accordion style) and won't stay in a straight line. There are suction cups on the bottom of the panels that might help if you're using it on a hard floor or smooth mat, but they're useless on carpet or textured mat.
My 17 month old granddaughter was only in the play area about 5-10 minutes watching sesame street one morning and got her leg stuck in the space between the rails. The Fire Department had to come and cut the post the free her leg out! I wanted to alert the manufacture directly but I was unable to locate a website or Facebook page. The spaces between the rails need to be closer! We loved this play area until we felt a safe zone became an unsafe zone.
Nice to keep baby out of trouble at home. Once he became mobile we had to do an "upgrade" as we noticed he was starting to hit his head on the X shaped metal bars. We tried some alternatives but the best so far was wrapping the metal bars with pool noodles (see picture). You'll need 8 pool noodles and some cuts (buy some extra in case you mess up). Use 2/3 of a pool noodle to wrap the internal bars and the remaining 1/3 to wrap half of the external bar. The pieces will also need a longitudinal cut along the length to fit the bar in. You'll also need some small cuts in the middle of the longer piece to fit the center rivet, where the mesh is attached to the bars. We got the pool noodles at the dollar store nearby for less than $10 and since ... full review
