Hi Ladies,

I'll be 37 weeks tomorrow and our OBS sent me for a growth scan yesterday.

Our little bub is measuring full term already with 3 weeks to go.
They said his head is already 40 weeks and his tummy is 'off the chart'. The sonographer showed us that his tummy is several points above the top end of the scale.

They estimate his weight to be 4.1kgs right now.

My OBS is keen that he stay in there until at least 39 weeks, for his own benefit, because although he's measuring big, it doesn't mean his lungs are ready etc.

I'm a first time mum and have no experience with this. Should I be booking in for a caeser or trying to birth a possibly almost 5 kg baby?

I'd always thought I'd have him naturally, but ultimately I just want both bub and I to be safe and healthy at the end of this.

Thanks for your advice/ experiences...

Both my babies were 'big' DS was measuring 40 weeks at 34 weeks.

I was lucky to have a very pro natural ob who told me to trust in my body and that he'd be there to help me through.  He never did a sizing scan as they can be very inaccurate.  He did estimate size by palpation and was 100grams off for DD and spot on for DS. Induction or c/s for size was never mentioned.

I was induced with DD at 42 weeks, due to being overdue, nothing to do with size. She was 4.6kg and had a 39cm head, I only had a graze, no stitches.

If I were you I'd trial labour, trust in your body,stay upright and let gravity help you! You'll be in good hands.  Good luck!

I have had 4 baby's and I have found that the bigger they are the easier it is to birth them. So trust in your body and know that you are made to birth your baby original.gif good luck

I had a 5kg baby naturally no probs! I don't have anything to compare it to though. He was measuring big from 34 weeks and I had a scan at 39 weeks that suggested he would be 5.3kgs

Sizing scans are notoriously wrong. Go with your plans, trust your body.

I would not be concerned about the growth scan. They are +/- 500gms and your baby may not put on that amount of weight in the next couple of weeks.
It sounds as though your Obstetrician is being attentive so I would be guided by his recommendations remembering that most of us carry babies that we can deliver.
Good luck. original.gif

I was also 'measuring big' by ultrasound, and bubs was predicted to be close to 4kg. He arrived 2 days over my due date at 3.5 kg, so not really big at all. He did however then feed like a trouper and doubled his birth weight in about 3 months, and is now a big baby lol!

Yup. I measured 42 weeks at 38 weeks. I was sent for a scan and was told bub was about 3.6kg. I was planning a VBAC and I was told I should consider a CS. I declined, had DS2 4 days later naturally and he weighed 3.2kg.

Trust your instincts and good luck!

Just echoing PPs comments - scans can be seriously inaccurate at predicting size, and bubs may not grow a great deal in the next couple of weeks anyway. My sizing scan estimated bubs was 1-2 weeks ahead, and her head 3 weeks ahead and would weigh around 4kgs. Born at 39+2 she was a petite 3.39kgs with a perfectly average sized head original.gif Either way, our bodies are amazing things and you'll be fine!

I would be guided by the Obyn. He would know best if you need a csection
My DD was born at 37 weeks and whilst her lungs were fine she struggled to feed (bf or ff) and the doc said it was because she was just that tiny bit early. Nothing serious but was stressful for us.

Again, just agreeing with the other PP's who've said that sizing scans are notoriously incorrect and I have rarely heard of one being accurate.  I would never base my decision on how to give birth on a sizing scan alone.

#12 I'mBeachedAs

Posted 30 December 2012 - 04:44 PM

Agreeing with everyone else. Scans predicted my son would be around 3-3.5kg. He ended up just under 2.5kg. Be guided by your obstetrician about your delivery.

My sizing scan was accurate, dd was said to be about 3.4kg at 36weeks and at 39 weeks she was induced and born at 4.4kg. I had an incident free induction and her birth was easier than my 3.3kg ds. Be guided by your ob, but my advice would be to not opt for a c-section as your first option, trust your body and your doctor and midwife. Good luck original.gif

My first was my smallest baby had episiotomy, forceps and plenty of stitches.  My biggest came out posterior with his hand by his head, didn't even need a stitch. I wouldn't worry

I was having a planned c-sec anyway  but was sent for a few growth scans after being high risk for DS (and no amnio). DD was measuring 4.5 weeks ahead at her 32wk scan. They said to me that even with a vaginal birth they usually just go ahead with delivery as normal.

Don't forget too that apparently a lot to do with the delivery is that not in the weight but the BPD (I think that is the one)

I had also measuring big. I had a size scan at 38 and predicted my daughter weight at 4 kg. She was born at 40 weeks and that is exactly what she weight, I started labour but had to have a cesarean at the end. I suggest you follow your OB advised and your body.
