Breastfeeding time

My baby is almost three months old and is breastfed which I feel super lucky to be able to do. However, he’ll sometimes eat for 45 minutes and then be hungry an hour later. He never goes longer than 2 hours between feedings. Is this normal? Is there anything I can do to extend the time between feedings? Is it just because he’s a big boy?

He is large for his age. He was 9 lbs 12 oz when he was born, he’s not even 3 months yet and is a little over 15 lbs and in size 3 diapers and 6-9 month clothes
