There's a saying amongst techies that gaffer tape can fix pretty much anything. That, and that it holds the world together. We've been having some difficulties getting the baby to sleep recently as he doesn't seem to like lying flat. We'd also noticed that he's taken to sitting in his activity chair really well. He'll happily spend all day in it, and, importantly, likes to sleep in it.

The difficulty we've got is that we have a sleep apnea monitor. Each sensor for this is rigid, and roughly the side of an A4 piece of paper. The activity chair is soft on all sides. Trying to put the two together was clearly going to be difficult.

I ended up gaffer taping the sensor across the back of the chair, so his back is on it. The top is gaffer taped in place, and the bottom held in place using cable ties (so that his weight doesn't cause the tape to stretch and thus lose contact with the sensor). The top is gaffered because the top of the chair is circular and cable ties won't hold on it without slipping.

It looks rough and ready, but it works. All those years of working in theatre have taught me something...
