Carbon monoxide poisoning

Then it would go off earlier, since CO is lighter than air - and, usually, warmer since it's coming from the combustion gases from the boiler.

Seems logical, though Which says:

Position the alarm at head height (your breathing level), but it doesn't need to be fixed to a wall (a shelf is often suitable). The alarm should be at least 15cm from the ceiling.

• A carbon monoxide Detector should be at least 150mm from the ceiling if fitted on a wall. Apparatus located in sleeping rooms or located in rooms remote from the fuel-burning appliance should be located relatively close to the breathing zone of the occupants.
• A carbon monoxide detector should also be placed close to sleeping areas particully if the risk is confined to that room, where the audible alarm is loud enough to wake up every person sleeping within the risk area.
• If the carbon monoxide detector is fitted on a ceiling, it should be at least 300mm from any wall and any ceiling obstruction e.g. light fittings.

Has your baby been ill too? If the CO was responsible for your illness, it seems strange that such a young child hasn't been quite seriously ill over the past year.

Carbon monoxide poisoning seems very unlikely with a functional CO detector. With levels required to cause symptoms it would certainly have gone off and as other posters have pointed out, babies are particularly susceptible to effects of CO so it is a good sign the baby has no symptoms.

Who made the diagnosis? Normally it requires measures of blood levels from an arterial blood sample.

CO2 alarms can be placed on either the wall or the ceiling, so long as its not too near the corner.
The reason for this is the way warm/cold air circulates in a room, air gets trapped in the corners and does not circulate there, so any co2 would not reach an alarm placed too near the corner, hence they need to be on a wall, more than 150mm from the ceiling OR on the ceiling more than 300mm from a wall(or other obstruction), to avoid them being in a 'dead' spot
