percentiles and predicted birthweight
No advice really but Im in the same boat. I have a teeny belly for being
nearly 7 mos pregnant, I look maybe 5 mos at best but the baby measured 3 weeks larger than average on ultrasound and fundal measurement has been about 2 weeks larger as well. My midwife says it's because Im tall (Im not really, 66in) For what it's worth, I was small with my daughter, measured small, didn't even look pregnant and she was 7lb 9oz at birth. With my son I was HUGE, I mean I couldn't see my feet by 5 mos, couldn't move. I swore I was having an elephant! Also measured big on all accounts though not as big as this one has been, only a few days off on ultrasound. He was 8lb 6oz. So that is why Im puzzled, I can't believe I'd have a big baby when I look so small! I dont know how reliable it is honestly... Kari mom to Kaylie (7) Noah (4) and #3 due Sept/Oct "Nancy" wrote in message om... My last two ultrasounds (at 20 and 26 weeks) indicated that the baby was at the 74th percentile for growth. Does anyone know a reliable source of info on the implications for predicted birthweight, provided the baby stays around that percentile? (This morning, at 29 weeks, I have a fundal measurement of about 32 weeks. Yikes.) Thanks!! Nancy |

Why, yes, I do. http://www.gestation.net/birthweight...ile_online.htm (works only with Internet Explorer, as best as I can tell). Just as an anecdote, mine was a bit below 50th percentile at 22 weeks. I consistently measured 3-5 weeks small. The midwife said I'd have a small baby. Caterpillar was 95th percentile for height and 75th percentile for weight at birth. Based on the calculator above, she was 55th percentile for weight among babies with the same gender, gestation, and maternal height and weight, though. Phoebe |

"Nancy" ha scritto nel messaggio om... (This morning, at 29 weeks, I have a fundal measurement of about 32 weeks. Yikes.) Hey Nany - I, on the other hand, at 27 weeks + 1 day, had a fundal height of 31 centimetres! However, my ob/gyn told me not to worry, she says FH measurements ares by no means 100 percent accurate. She says that in my case it might be influenced by the way I'm carrying the baby (sort of in the middle, not high or low). Also, she is not worried because I had an ultrasound at 26 weeks when the baby's size was exact for the gestational age. Elly 27 weeks + 4 days EDD October 6th |

Thanks to everyone for your replies!
As an interesting aside, my endocrinologist (I neglected to mention in my first post that I'm a Type 1 diabetic, which does predispose me to bigger babies, although my first was 50th percentile at birth for height and weight) told me that some studies suggest that women pregnant with their 2nd or subsequent children have a better-than-50% chance of predicting birthweight, in some instances with accuracy comparable to ultrasound!

"H Schinske" wrote in message ... wrote: I thought they were *more* reliable than ultrasound? In any case, it isn't quite a fair comparison, because the woman has the advantage of knowing what the first baby *did* weigh, so it's a reasonable bet, if both babies are full term and healthy, that the next one will be less than a pound different (obviously there are exceptions! I just mean you'd have about a 75% chance or something like that). Is there data that they'll be less than a pound off? DD was 7lb 9oz. As I got to the end of my pregnancy with DS I was guessing he'd be born between 9 and 10 pounds, while my midwife guessed 8lb 4oz at 40 weeks and said 4oz growth per week would be a good bet as well. He was born at 41w4d and was 9lb 11oz, so more than two pounds greater. |
