I have a beautiful back garden mainly consisting of brick patio areas, lots of tubs and nice garden furniture (we bought this house before children arrived obv!). There is no grass at all however and 23 mo DS loves to be outside. He is into everything right now, nothing is safe, and he is particularly fond of falling over! His knees are a mess despite my best efforts. Does any one have any bright ideas as to how I can make it safer for him to play in the garden? I really don't want to lift the brick and replace with grass (the costs would be massive) but I wondered if anyone had seen/bought any garden play or crash mats? Any good? Any other ideas?
