Hi there, my second baby is due in December, when my 1st will be around 20 months. I think for the first 6 months we'll probably just turn our Uppababy vista into a double, but it'll be a bit cumbersome I'm sure so I'd like to invest in a good, manoeuvrable side-by-side pushchair once the baby is sitting up. From a first glance, the out n about nipper looks quite good, but would love your recommendations. Thanks so much!
