I have a 7 month old who is beginning to get active. We have a very small (London) 'garden' which is really a patio and although it would be nice for ds to spend time out there in the summer, need to keep him safe. Also starting to think how best to safety-proof the house. What is the current thinking on playpens? I have seen one - think its made by Babydan, which doubles up as a safety gate. Anyone got any thoughts?
