My husband and I are going to be in AMS for 3 months with our 9 month old. We have a great Phil and Ted's 3-wheel stroller but we think it might be too big to maneuver through all the crowds. But a compact umbrella stroller probably wouldn't handle cobble stone streets very well and it wouldn't be as comfy for long walks for our son. We definitely need a stroller for a 3 month trip. What should we do?
Since your trip is long, why not consider buying one once you get there? Your options will be what the locals use. And based on my experience as a parent, umbrella strollers aren't comfortable for long periods of time. My kids were crabs after a very short time when we had to use them.
I like the umbrella strollers because they fold up and don't weigh much. I recall a lot more smooth surfaces in Amsterdam but I'm sure there were cobblestones somewhere. Everything is built for bikes so bridges have slopes rather than stairs and a stroller isn't too hard to negotiate.
