Hi and thanks Gemma, I read your previous post and went searching for more information about 'The Natural Way to Better Babies' book but unfortunately, couldn't find much online.. I like the idea of the epsom salt cushion and might try that.. and hopefully it'll ease my mind a little. Just that being only 7 weeks, baby is still only very little (the flight is 8 hours) and I wouldn't want to jeopardise anything in the future. I'd feel absolutely awful if anything went wrong, I'd never forgive myself.
