What factors afffects baby's birth weight?

[~clover~]

Well, I don't think there's anything you can do TBH.
Our babies were,

DD1 - 3.320kg (7lb5oz) 8 days post dates
DD2 - 3.885kg (8lb9oz) 7 days post dates
DS - 3.840kg (8lb7.5oz) 2 days early
DD3 - 3.450kg (7lb9oz) 5 days post dates

So no matter when bubs is born, they will just weigh what they weigh. I am not a big person. I do not believe for a second that your weight or gain have anything to do with it. I put on minimal amount of weight (5 - 6 kgs) in each pregnancy, but had good sized babies. They all have the same father & didn't get bigger the more I had as people expect.

Smoking 'may' make a difference, but I highly doubt you'd want to go there, & a friend of mine's DS was 10lb 10oz at 16 days post dates, even though she smoked through her pregnancy. Another friends bub was only 6lb9oz, less than her first, at 7 days post dates & I believe the smoking may have had an affect there.

Its all about the baby itself & chance. All I can say is do what you can do to have a healthy baby. Your body will take care of the rest.
I really don't think bub's size was the issue. The position of bub was more likely the problem.

What ever happens, good luck with your birth

I lost somewhere between 7 and 10 kilos last pregnancy and in the 3rd tri only put on 5 kilo of baby weigh...and P was a normal 8 pound 3 ounces...so I don't think exercise or HEALTHY weight loss/gain has any effect on the bub. That's not including dangerous eating habits, obsessive exercise or gestational diabetes of course.

My SIL was a VERY heavy smoker during pregnancy and she only had a 6 pounder, but not sure if the smoking had anything to do with that directly...although I have read that it makes babies smaller.

i have never smoked and i am regular ish height 165, had 2 babies on their edd's, 5lb 13- 2.65 and 6lb 2 oz- and there was nothing known to cause their weights. ate well and exercised, put on 20kg eeeeekkkkk! but they are both fine and healthy now.
I agree that you just have what you have, unless there are gd or complications i guess.
one thing i might add- i hate people saying " oh you had it easy" coz they were small. I hate that!

hope you have a fabulous vba2c x
