Hello all i am just curious to see if your first borns were similar weight to your second borns or were they completely different??

My son was born at 40 weeks and 4 days and he was 9 pound 11 ozs and 54cms long. Just have read and also heard that the second babies are a quicker labour but bigger baby wanted to know if there is any truth in it from all your experiences. Thanks i know there is no way of predicting weight and gestation/labour times but was curious....
