I had been using the colorful 8-panel North States baby gate from the time by babies were 6 months-one year. But once they were learning to climb the gate with their toes in the little holes (and use their baby muscles to pull the entire gate down), I knew it was time for a more sturdy option. This fit the ticket, it's not as large as the North States - but plenty large enough for toddler twins (with more than enough room for mom and/or dad to play in with them as well). It's also a few inches shorter in height to our old play pen, but it's not an issue with our 28 & 29 inch boys because the openings/holes on the play pen are low enough that when they step on them, it's more than tall enough to make them unable to climb over. ... full review
The North States is one of the best play yards that comes with a high-quality 8-panel-colorplay. This play yard offers the enclosed area up to 34.45sqft and 26-inches height. It is an outstanding solution as it offers a safe play area for babies and you can use it for indoor or outdoor. It comes with non-slip pads so that you can place it on any surface even on hardwood floors as it will not scratch the floor. The play yard can withstand any kind of weather as it is designed for outdoor safe as well.
We have a new puppy. We got one of those wire pens for him. Unfortunately, he almost immediately figured out he could climb the cross wires! He was out in a flash. SO we got this pen. It is almost perfect. It will be perfect when we get done. The bars are in general about two inches wide. Those he cannot get through. But the gate is a different matter. The bars around the hinge and latch areas are about a half inch wider--probably to accommodate the mechanics of the gate latch and hinge. But that is just enough wider that our puppy can get his shoulders through. Maybe the rest of his body, but we intervened.
