question that I just thought of. if my blood sugar has been fine with what I was eating before does that still make my baby really big? the doctor has said He s big for 35 weeks and kept asking me how my sugars were and I've only had three high ones and have stayed away from the stuff that has made them high. it doesn't make sense to me and it worries me...lol
