Our garden has a patio area then a wall up to the grass. I have no idea how I am supposed to baby proof it, I can cover the stairs with a fire guard, but I don't know what to do about the wall. I can't put lo on the grass either in case she falls back to the patio ! We wanted to have a BBQ for her birthday, but I don't know how we could manage lots of babies in the garden! An ideas?
