Hi, I have dd1 2 1/2 who is starting to want to walk now and dd2 11mths old and am thinking of a 3rd child??? Mad I know. Trying to find a good pushchair. At the mo I have a britax excel travel system and a buggy board but my dd1's head is just at handle bar height so she bangs her face sometimes. I have a graco stadium duo tandem but this is very heavy. Plus don't know whether to stick to a tandem as when d?3 born dd2 would be just over 2. So much to think about.
