Sorry, I'm not the person you are looking for as I am type 2 and wasn't even pre diabetic when I had my babies, very many years ago. I just want to tell you that my first born was born at 30 weeks and weighed 1.693 kgs at birth. It was officially at 30 weeks because my cycle was never very regular so that's what 'they' said it was - 30 weeks. They would not listen to me when I told them that I knew without a doubt that I was only 29 weeks because my husband was working away and we didn't see a lot of each other and it was therefore easy to pinpoint the day I got pregnant.
When I had my second baby, they said I would definitely need another caesarean, because at 30 weeks he was 'very big'. When he was born full term he was exactly average weight - 7lbs 11 oz. - no caesarean.
Now, I understand I was so lucky not to have the complications you have with blood sugars etc. I also see how worrying it must be for you, all I can say is just keep going, do the best you can with your BGs because that's all you can do - your best: one day at a time, even if you don't find the perfect buddy to help you , because you don't have too long to go now, but this is the important stage where babe could actually pile on the weight. My babes were naturally bigger than average at 29 weeks, maybe your one is too. Try not to worry (yes impossible, I know) because stress makes your BG's fluctuate even more.
I am sorry if I am upsetting you with any of this, it's not my intention, I just feel for you even though I have never been in your situation. Because I have not been in your situation I may have said things clumsily in this post which therefore cause hurt, if that's the case please throw those bits away and just be encouraged that you can get through this and everything can be OK in the end.
Ok, so hopefully this post will at least bump your thread up the list a bit so that more people can see it and then you will have more chance of finding that buddy
