Is it heavy for 37 weeks?

Currently pregnant with second baby and at 37 weeks he’s weighing 3kg which I find quite allot. My first born was 2.5kg when he was born at 38 weeks.
I’m worried to the point that I’m thinking of opting in for c section as in another few weeks he might be nearly 4Kg which is considered dangerous to birth?
4 weeks ago he was 2.2kg and now 3kg.
Anyone thinks that’s allot?

I’m really anxious.

Why would nearly 4kg be dangerous to birth? Do you have particular health circumstances?

If the weight is from a scan then they’re not exactly the most accurate. Presumably the sonographer told you the centile your baby was on? If you’re anxious in pregnancy, it’s best to talk to your midwife and go through your different options, but lots of babies are born at 4kg (or more!). Call your midwife and explain about your anxiety.

Where are you getting that that is a dangerous birth weight?

Lulu89x · 01/05/2025 18:45

These measurements are not always accurate so try not to stress yourself out

My first dc was 4kg. She was 5 days overdue. I gave birth naturally and it was fine. It might feel daunting to you but it's not dangerous.

A high centile baby isn’t a “risk” or “dangerous” to birth. Do you have some other complications going on?

MathsMagpie · 01/05/2025 21:18

None of my 3 were anywhere near their estimated weights from the scans, although some people seem to get better ideas. It’s not an exact science, try not to panic!

4kg I don't think is considered dangerous to birth. My little one was bigger at 10 pounds 1 (c section for this obviously)

He's perfectly healthy. I also know lots of babies born around 4kg.

It can be. My baby was tracking bigger and it was recommended I have a c section for risk of birth injury. I thought this was common practise tbh.

I was scanned in labour and baby estimated at 8lb 3. He was born 20 hours later (36w5) at exactly a pound less 7lb 3. The estimates are really not great once you're that far along

I had my growth scan last week at 37 weeks and when they told me 2.9kg I said “oh so he’s small?” 😂 the consultant said no not small, bigger than average but not considered a big baby. I think it’s only 65th centile or something. I wouldn’t worry!

Strange. I measured over 95th centile with my first, born 97th centile, not one doctor or midwife suggested a section due to size. Roughly the same measurements/ predictions this time and no suggestions of a section because of a big baby.

ncforschoolhelp · 01/05/2025 21:36

The estimated are almost always quite wrong. My oldest was estimated at 10lbs at 39 weeks, he was 8lbs at 40 weeks. Youngest estimated v small (less than 6lbs) so had a c section, he was 9lbs at 37 weeks. He would have been a whopper!! M

Ignore the estimated weights.

I'm in Scotland so maybe that's why. NHS info below.

'In NHS Scotland, a caesarean section is usually recommended for babies predicted to weigh more than 4.5 kg at term'

This is very sensible to me tbh.

My DD was born at 37+2 and she was 2.8kg and tiny. I wound take their predictions with a pinch of salt.

I’m in Scotland too. Must depend on the hospital/ consultant/ local authority area.

It really depends on the weights they've got for you. As far as i'm aware it's a general guideline if baby is expected to be over 10 pound.
