J was, and still is a big baby. Can't remember what centile he's on, but he outgrew his 0-3 month at 2 weeks. Now at 11 months, he's in clothes for a 18-24 month old. I get numerous people comment on his size. My niece is 6 weeks older than J, and is tiny compared to him. I dont worry about his size, if anyone says anything, he'll be big enough to bop them one, haha.
