Oversupply of breast milk?

Helene

Hey ladies! I’m a first time mom, my baby is one month old today. I believe I have an oversupply of milk - when she feeds it leaks out of her mouth, she coughs, gags, pulls off and it sprays everywhere and the leaking ... oh god the leaking! I’m not complaining at all BUT I was wondering on moms’ experiences with block feeding? The poor girl will feed for 5-10 minutes max and so I’ll think she’s satisfied but then she’s hungry again 30-45 minutes later. I love breastfeeding her but it gets tough when I’m doing it every hour 24/7. She gets super gassy too and fusses at my breast, pulling off, crying, and generally uncomfortable. Any advice?
