I am sure when I have a baby I will have a massive buggy and look back on this and judge myself.
But at the moment I am SICK to death of being barged out of the way by people with huge buggies, or people with buggies walking next to each other so there is no room to get past on the pavement, or not being able to get to a bit of the shop because a huge buggy is there blocking the way. I asked someone to move their buggy today (politely) in a small shop and she tutted at me. Grrr.
