So, this January we are expecting our third bundle of joy, and I'm trying to wrap my head around how to travel with all of them. I will have a newborn, 2 year old, and 4 year old. Do I need to buy a stroller that seats two and then my (then) 4 year old can go on one a "glider board?" Or, have you found that just a double stroller works?

I ask because I currently have a Britax B-ready, and I can't put a glider board on this stroller if I'm using the extra toddler seat. So, do I need to invest in a City Select?
