The 4moms Breeze Play Yard is a high quality, large and durable playpen. It also contains a bassinet and changer for three products in one. This playpen is literally a breeze to set up (see the video below for details). The mattresses (yes, it comes with a separate mattress for the playpen portion and the bassinet portion) each come equipped with Velcro to attach directly and securely to the playpen unit. This product comes with a carrying bag, so technically you can use it for travel, though it is on the heavy side at 25 pounds. Some consumers say that they have a difficult time getting all of the pieces back into the bag for storage or transport. The 4moms Breeze Play Yard will set you back $299.99, but you are getting a high quality product that will last a long time, through multiple kids.
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
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
