I am going to ttc this years and I wanna start looking for double strollers. I will be using a Graco infant carseat. And I have a toddler. What's a good stroller that will allow me to latch the carseat into it?
Since your son is almost 2yo, I would definitely consider something like the Baby Jogger City Select, Phil & Ted, UppaBaby Vista w/jump seat...etc. they are all car seat compatible single strollers that convert to doubles when needed, then back to a single when not.
Depending on when you decide to TTC this year, if your son ends up being 3yo when baby is born...I wouldn't buy a double at all. Get a nice single stroller and a wheeled board for him to hop a ride on! Our son was almost 3 when DD2 was born and he loved the wheeled board...it was like a skateboard to him.
