Moving the three smallest kids in the family around, perhaps only to get them to sleep, is a continues problem.
To handle the problems we have no less than three prams/strollers.
The obvious one is the one we often refer to as "the panzer cruiser Potemkin" due to its size and weight - that makes people move out of the way when we walk down the street.
With this pram we can walk around in and to things in our neighborhood and each kid can sit or lay down as we/they choose.
But Potemkin come with a number of new problems, and they are mostly due to its size. First: It won't fold together very well and we haven't even tried to get it into the car. Second: It's to wide and long to get into many places, like the doctor's office or the local bus.
So we needed another "vehicle": Our Baby Travel Dublin.
This is really a stroller for two kids, but you can attach an extra seat in the front. Only two kids can lay down and sleep in it, and that is its biggest limitation for us.
But quite often we do find that two is enough; perhaps only two kids need to sleep at a given time, one kid can be carried or ride in another stroller. When we take the bus downtown the extra seat is convenient; three seats but the stroller is still just the size of a two-kid stroller and we no problem getting on the bus. But the kids need to take turns sleeping.
Pros with the Dublin is that it folds really well and is easy to put in the car and still have room for bags - or another stroller. The swivel weels also makes the stroller easy to maneuver - very unlike "the Potemkin"...
When we are two people that can push strollers, and all three small kids are coming along we usually use the Dublin along with our third vehicle, a Teutonia Timmy.
This is a basic stroller that folds well, allow a kid to lay down compleaty to sleep. We're happy that we realised that both the Dublin and the Timmy can be squized into our Ford Galaxy while all seven seats are in use!
