34 weeks pregnant with twins?

Question

and the u/s shows that one of the babies is smaller. She is only in 10 percentile. She was in 5 percentile two weeks ago. So it's a good new that she is gaining weight but still is not average weight. I will be induced in 36 weeks. My question is, did any of you have a u/s while preg and the weight of the baby was completely different than they told you during the u/s. I know u/s is not 100% accurate. I am curious to know now that I have only two weeks left,I really want my baby to be at least avg. weight.
Thanks.

Answer 1

Ultrasounds late in pregnancy can be off up to 2lbs either way. With my first the sOB said she'd be about 9lbs and she was 11lbs. With my second he *insisted* my son would be at least 12lbs. He was 10lbs 6ozs. I do not trust ultrasounds for weight estimations. It's all an interpretation of measurments and different people can interpret them in different ways. I'm sorry they're forcing you to have your babies early. They'd be much better off in-utero until you go into labor on your own (IMNSHO).

Answer 2

My sister had twins, as have others I known, and you should know that one or both twins are usually below average weight. Remember also, that if you are induced at 36 weeks, that is slightly earlier than most non-twins are born, and so your babies will be slightly smaller than they would be at 40 weeks. (It is also common that one twin is smaller than the other.)

Also, remember about statistics: half the people born are less than average. For every 1000 people, 100 are in the ten percentile. Someone has to be smaller than average, and it doesn't necessarily mean anything bad.

The smaller of my sister's twins was a little more fragile when first born, but grew out of it within a year or so. Not significant. Don't worry. (Well, of course you will worry, but just try to remember the reason you are worried is because it is natural for a mother to worry, not because there is good grounds for concern.)

Answer 3

It's very common for one twin to be larger than the other; it has to do with which twin gets the most blood in utero. It's also very common for twins to be slightly under the birth-weight for a single, full-term baby. Your doctor is showing good judgement by inducing you at 36 weeks, so you don't have problems with placental insufficieny. Your babies will be well-developed at 36 weeks (they're almost certainly quite viable even today) and able to function in the world. Your baby may not be "average" weight for a full-term baby that developed alone, but I suspect it will be well within the average range for twins.

In the unlikely event of complications, that's what the NICU is for; I read a story just a few days ago where a ten-OUNCE baby had recently survived and gotten to go home, so your babies have it made by comparison.

Congrats!

Babies in utero grow alot in a week or two! I've had 3 of my own, and am 18 weeks along with my fourth. Never had twins, but i do know that usually one of the twins is smaller than the other...one twin is more dominant and recieves more nourishment. Most multiple pregnancies work out just fine...and believe it or not, they consider any weight over 5 lbs. avg. weight. Good luck to you!

Answer 5

i have had us with all of mine and my oldest was suppose to weigh 3 lb but weighed 5 lb 10oz my last child was born 36 weeks and was us at 36 weeks and they said he would weigh 4 lb he weighted 5lb 9 so my advice is eat as much as you possibley can during the last week because that is the critical weight gain point for the child so next week eat all you can eat it will help babys gain the weight but yes us has been wrong on the weight of all my childeren

Answer 6

I have friends that had twins that had that problem. Their girls were a full 2 lbs different. The smaller had to spend the night in the nursery, but she is a healthy almost 3 year old now.

Answer 7

I was 34 weeks when I had my 3rd son and I had an ultrasound round 2 days before he was born. They estimated him to be around 4 lbs 3 oz and he was born at 5 lbs 2 oz....

Answer 8

I gave birth to frat. twins at almost 37 weeks. U/S all along showed them at the same weight, my girl was born 5lbs 11oz. My boy was 7lbs 4oz. My little girl didn't get as much of the blood supply as my boy, but she's also naturally petit. She would have been little had she been a singleton anyway.

Answer 9

My son was almost a pound and a half bigger.I'm sure your babies will be fine. She still has two weeks to gain.

Answer 10

weight on the us can be off by about a pound, but it doesn't usually happen that often... I would say maybe off by like 4-8 oz.. Don't worry too much though, I am sure your doc knows what he is doing.... Congrats.... you are gonna have your hands full!!!
