I'm a 20/22 and BMI of 36. I had DD at a consultant led unit 7 miles away [which was 1 1/2 hour drive through deep snow] as my BMI was high. I had MW led care all the way through. I did have an epidural, which an anesthetist administered. Was a lovely experience and was glad for the pain relief. MLU is at the end of my road, I can see the MW coffee room out my kitchen window, I was hoping to be discharged to there, but DD needed consultant monitoring as she was under 6lb.
Though I love my food, I eat balanced meals and exercise regularly, recently stopped BF and my weight went up two stone, couldn't believe how much extra I was eating. Just got my eating under control when found out expecting DC2. I know I will be back up consultant led unit and am not worried.
One MW did freak me out last time saying I would get GD and would have a large baby and would end up with a CS. Which was absolute spaff. Next MW I queried all this with confirmed spaff, they were risks but not set in stone, she was on the larger side herself and had a waterbirth at the consultant unit recently with no problems, sent home same day.
The only thing that bothered me [so much I did put it in feedback] was that all my care pre delivery was at the MLU and had a very brief tour of CLU but didn't get to know the staff like I did at MLU, knowing they wouldn't care for me or my baby on delivery. Also because they were MLU they had to refer any query about my delivery to CLU as they couldn't answer the questions as no knowledge of working on the CLU.
You may be referred to a dietician, I was last time and have been again. My food diary was healthier than some standard BMI pg. Last time I had a health in pregnancy grant for maintaining healthy weight gain, of course there is none of that now.
