    Consecutive babies bigger than older siblings?

    I've heard from a few people that their 2nd babies were bigger at birth than their first (talking about full-term babies 38-42 weeks gestation) and that 3rd were generally bigger again.

    Is this quite common, or have many of you had 2nd babes smaller than your 1st?

    This could be an interesting poll if there are any moderators out there who could set one up?

    Yes and no, it all depends really. But its mostly just anecdotal evidence and no real 'proof' kwim? In my case however, my second bubs was smaller and then the third and fourth were bigger again. (DS 4.18, DD 3.85, DD 4.32 and DS 4.56). was told though that if #2 was a girl, then she could be smaller than my first.

    I can set up a poll if you like, just out of curiosity.

    I only have a sample size of two, but no. 2 was smaller than no. 1. Flynn (no. 1)was 3.9kg and Oliver was 3.89 - a whole 10 grams less. It was all in head size - they were the same length but Flynn's head was 2cm bigger in circumference.

    My two were almost exactly the same (3.5kg, 3.75kg)

    DD1 was 3385 grams 48cm long HC 34cm born at 39w4d
    DD2 was 3535 grams 52cm long HC 34.5cm born at 40w5d

    So between # 1and #2:

    Weight was 150grams more
    Length was 4cm more
    HC was .5cm more
    8 days difference in dates

    My 1st was 3lb 12oz. - but born at 32 weeks gestation
    2nd was 6lb 9oz - born 38 weeks
    3rd was 8lb 13oz - born 39 weeks 4 days

    My excuse for not having a fourth is that if I follow the trend, number 4 will be over 10 pounds and overdue!!!! Not very tempting

    My first was 6lb14oz, 20.5 inches, born at 40+1, second was 7lb10oz, 21.5inches born at 39+1, and third was 7lb8oz, 20.5 inches, born at 40+1. We're fairly steady, I guess. For me, it matches fairly closely the amount of weight I put on during pregnancy - the least with DD1, more with DD2, and slightly less than before with DD3.
    My mother had 8 babies, all around 7.5 lb. The heaviest was her fourth, which was just over 8lb.

    Cricket, it's interesting to hear you mention your weight gain during pg - I was the opposite and put on less weight with my biggest and the most weight with my smallest. For me even their length increased with their size too.

    hmm.. there needs to be a 'second baby was bigger than the first'... coz the first option makes it sound like I have lots of babies! hehe

    I know you wanted full term babies.. but I figure mine counts even tho she was prem LOL.

    DS was 6lb at 37 weeks
    DD was 7lb 14oz at 34 weeks

    bit scared if we go for #3 and it's full term! LOL

    Yep, my births confirm the theory that each baby gets bigger.

    DD 7'10" born at 42 weeks
    DS 8'8" born at 41 weeks
    DS 9'0 born at 37 weeks (that was amazing!)

    Ds3 8lb 9oz - 38 weeks
    DD1 6lb 12oz - 36 weeks
