Baby’s too heavy for the Bjorn. And the bassinet/car seat/stroller system you had to have has gone the way of Craigslist.

So it seems wrong that while a lone umbrella stroller stands in the garage (finally!), we’re suggesting that you add a new item to your arsenal. But we are — the Magic Stroller Bag.

On first sight, the small and unimpressive package doesn’t seem worth its $72 price tag, but the aptly named lightweight product seriously transforms your toddler’s current mode of transport. Unzip the pouch (it folds into itself), unfold the bag (with roomy interior storage, an attached key ring, and an easy-to-access outside pocket), place the silver grommets over the handles of your umbrella stroller, and you’ll be sold.

No more balancing a tricky tote or digging through the underbasket to score a sippy. Plus, it comes with a detachable strap, so if you need to close the stroller for lunch or a spin around the playground, presto chango: Just sling the bag across your chest and go.
