How much milk to drink?

Hi Mummies! I’m a FTM. How much milk should a 5 months 2 weeks baby drink? My LO takes 165ml 5 times a day. I have low supply of BM, so she only latch on once a day for comfort or nap. But she weighs 8.3kg, already at the 97th percentile of the weight chart. My hubby kept telling me based on her weight, she should drink more than the amount we are giving so that she can sleep longer stretch at night. Sometimes when the baby fuss or cries, he think she is hungry. But my baby is peeing and pooping regularly everyday, and is gaining weight. So I don’t see the point of giving more milk to her. In fact, I’m concerned why she is so heavy. Is the amount of milk too much or little for her? #FTM #firstbaby #pleasehelp
