My younger nephew was big like this as a baby (mom is short like me, but dad is really tall). Most babies seem so tiny and fragile that they freak me out, but not this kid, he was solid from day 1. I'm a childfree weirdo so babies, especially newborns, kind of scare me but I was comfortable holding him from the get-go. I used to joke that if he got too heavy I'd just set him down because I was pretty sure he could just walk away on his own. He's 5 now and not that much smaller than his 10-year-old brother. Literally every single person's reaction to seeing him for the first time is, "Wow! What do you feed him?!" He's not even chubby, he's just ridiculously tall and very solidly built. I'm scared to play-wrestle with him because, frankly, he's stronger than I am. I'm predicting he's taller than I am before middle school.
