So, I did what any modern mom would do. I searched online for a solution. That's when I found the Summer Infant Plush 'n Play Changing Pad with removable Toy Bar for entertaining baby on Babies R Us' website for $39.99, which is around the same price as my previous changing pad that didn't come with a toy bar. Apparently, Summer Infant is the only brand to offer a toy mobile of sorts with their changing pads, but I don't know why more companies don't do it though, as you can also easily remove it too in a second.
The toy bar is foamy with soft terry-cloth jungle-themed toys dangling from it. I was afraid it might be hard putting the boys down under it, but it hasn't been a problem. Plus, as I said, if they do hit the bar on the way down, the whole thing is soft like packaging noodles. You can also place the bar in the middle, bottom or way up at the top like I did. Since using this new changing pad with built-in toys, the boys went from complaining to enjoying lying there. They are now busy reaching up for the toys, even before I lie them completly down. It's funny to watch their little hands stretch out for it. It also has a safety strap, which we've now had to start using, since days of leaving them alone on there are over.
Bottom line: I wish I had registered for this changing in the first place and that I had it months ago to entertain/distract the boys when they first started playing. The old pad is now at Grandma's house.
