Feeding on demand

Jeanny
I've seen quite a lot of posts mentioning routines with scheduled feeds throughout the day. And I'm here like how does it work? I'm FTM and still feeding my girl when I see hunger signs, sometimes she feeds only for 5min other times for longer. She is usually hungry around the same period of the day but there are days she feeds much more frequently. It's all fine for me. But I wonder if I'm doing it wrong... Any other mommy still feeding on demand at 15 weeks?
