My wonderful sister was safely delivered of a little girl this evening, both absolutely fine. After all our worries about her gestational diabetes (which was ignored by the hospital for 10 nightmare weeks) I can't tell you how much of a relief! Dire warnings that baby would be huge turned out to be an exaggeration - 8lb 6oz, only 2oz bigger than my ds. And no special care needed either, hurrah!
Thank you to everyone who posted about diabetes. Bless you
