Hi, our dd has slept through from very early on but because of a nasty chest infection over christmas she has started waking during the night again. We thought once she was better she'd go back to sleeping through but the last few nights she's been up around 11.30pm until 2am waking up every 20 mins because she's moved and bumped her head on the bars of the cot. According to what I've read bumpers aren't suitable for babies who can sit unaided so any suggestions?
