Hi there, good luck first of all. Not sure about under 6, is that the recommended? Mine was 6.8, down from a couple of years of regular 8s, and I got pregnant the first time around? I'm 41 so am quite surprised to say the least!
My last two children were born when I was type 1 and they are fine, just control all the way, test and test and test, and walk/exercise after every meal/large snack, it really works.
First child was HUGE, 10lbs, born 'naturally' and second not quite so big, 8 and a half pounds, born under general anaesthetic and recommended C section as the first 'natural' birth was so horrendous!
