We bought a Maxi-cosi mura 3 which is suitable as an offroad pushcair up to 4 yrs or something.
Combined it with a pram body/carry cot for early months when visiting family on foot – meaning we can detach pram body and it can be used as a cot at friends and families homes. The cot folds flat for storage if you want to put that and frame in car.
Also got the maxi-cosi cabriofix car seat that attaches to the main pushchair body that will be used for walks/shopping when we have driven there. The car seat bases are available quite cheap on ebay we paid £35 for one.
After about 6 months I reckon we will only have use for the pushchair itself.
This is all in a perfect world though as ours isnt due until xmas time.
The idea of this one was that we have a springer spaniel who will need walked twice a day still so it needed to be offroadable and sturdy – it will be used from our door and not really used as our car solution (got a zapp from ebay for that but they are >6months or birth with the cabriofix seat)
