Finally someone does it! While previously unpopular, the Aria solves the VERY real problem of a stroller industry lacking in side-by-side options for siblings that also take a car seat! When my dd was born two years go, kid you not, there was NOTHING on the market for my toddler and my winter baby. It took me a full year past her birth to finally buy a Mac twin. However, for this new baby I am thrilled to have the 60/40! One seat holds up to 60lbs, the other 40lbs, making it perfect for tots and infants alike. The full recline, full generous canopy make it ideal for keeping nosy strangers hands off baby as well! All the while, older dc can sit up and interact with the world while mom does the very necessary errands. Thank you Peg. You finally did it!
