Breastfeeding worries

Bri

Okay so I have small boobs. I’m about a B cup. I am pregnant and wanting to breastfeed. My boobs grew a little bit not huge. I am still wearing my same bras but they have filed them out a lot better with minimal spillage. I am worried that I won’t be able to breastfeed. Is this worry substantiated or just normal fear? Did anyone have minimal growth and able to breastfeed just fine?
