Newborn always crying and wants to latch

Hi Mummies, I am a first time mum here and I am looking for advise on breastfeeding as I am really confused and worried on what to do. My baby is 12 days old now and recently I have noticed that he cries a lot even after latching. It seems like he always wants to latch. Right after latching he shows latching cues again. In one sitting he latches for approximately 45 mins. I am super confused and worried on what could be the reason here. Family is suggesting that I introduce bottle as he latches for too long very frequently but I don’t want to as I feel that he won’t latch then. Any mummies who experienced this ? What shall I do ? I am feeling sad that even after frequent latching it seems that baby is hungry that is why he cries. Please help mummies 🙏 #advicepls #firsttimemom
