I've got to make a trip into London with my toddler to meet some friends, I don't live in London so I don't know how this all works.
My options are city mini, 360 nipper and I have a sling that DS can go in. I'm also pregnant (with mild SPD) so I don't really want to put my son in the sling all day. I also have numerous reins etc for keeping him attached to me.
So what would you recomend? It would be on a Saturday.
