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
Many play yards, such as the Graco Silhouette discussed in Types, offer a bassinet that covers the entire length and width of the play yard. That is a good feature because it reduces the likelihood that your baby will fall into the play yard. But a baby could still fall outside of the play yard so stop using any bassinet attachment once your baby can push up on his hands and knees. The Safety 1st Travel Ease Elite Play Yard (about $112) also comes with this type of bassinet, and a changing table and removable toy bar. It measures 30 x 46 1/4 inches and has lockable wheels.
Perfect for a variety of different uses. Having 3 kids under 5, I've used my fair share of baby gates and play yards. The Evenflo play space is very portable, lightweight and easy to fold down and take on the go. You can add and remove sections with a simple push of a button. I'm currently using this gate to block off my fireplace from my one year old who's fascinated with climbing on it. Also, I will be using it during the holidays to wrap around and block my kids from getting into the Christmas tree. I would recommend this gate.
