I have an O-Baby Sport pushchair and my sister's old Phil and Teds. DD1 is just 3 and DD2 is 2 months. I find the Phil and Teds almost impossible to easily/quickly put up and down or get into the boot etc and it has just suffered a puncture which is way more technical than I can manage! So I'm thinking about DD1 riding along on the back of the O-Baby. Can anyone recommend the best type and make of thing I need for her? Apologies if this topic has been done thousands of times already, I've no time to do a proper search as the 2 month old requires total attention except during 15 min naps!!
