2 week appointment weight

Baby had his 2 week appointment yesterday at 11 days old. He weighed 8.8 at birth, 7.15 2 days later. And yesterday was 9.3. Is this normal? Dr just said he was super healthy and looked great. He is only breast fed and I haven't pumped at all yet. How much did your babies gain by 2 weeks? I'm mostly wondering if this baby is going to grow up to be a giant beast! Lol!
