I know this is going to sound like I'm a complete fool but I am worried sick about something and don't know who to ask. It regards my gas hob. Whilst cooking this evening - I turned the gas down on the hob (to tend to my ds) then served up dinner, played, bathed and put my toddler to bed. On returning downstairs to start my dh's dinner I found that I had forgotten to turn the gas off on the hob - however there was no flame - in other words it must have accidentally blown out. Being 37 weeks pregnant and a worrier at the best of times I 'm now convinced I have poisoned my unborn baby, ds and myself by letting gas escape around the house. Can anyone advise here?
