Second time moms stroller advice

Michelle • 27 years old Wifey & Momma of a 3 year old. Currently expecting #2 in July 2015
So I'm looking at what double stroller to get. My infant carseat is from britax and I'm not liking the double stroller for britax cuz it's a side by side stroller. I have 3 going on 4 yr old so I need something that will be easy, light and functionable for a toddler and infant. What u ladies getting out there.
