2nd baby birth weight experiences

My first baby was 7lb 2oz when I gave birth at 40 weeks. She dropped to 6lb 10oz when she was 3 days old and she was in tiny baby clothes. She was quite small. I was a 6 lb baby and my husband was a 10lb baby at birth, my husband is also ginormous (6ft 2 and big)... I’m expecting a boy this time and I’m actually a bit worried about how big he’ll get. I was just wondering if anyone would like to share their experiences on the weight of second or more babies, especially boys weights as I’ve read they tend to be bigger anyway.
