Sleep @ night !

There’s so many different opinions on this , and I’m sure I’m overthinking it . This is my first child so I’m not surprised if this is such a minor concern for others , however when it comes to bed time I wake my daughter @ about 2 hr and 30 min into her sleep to feed. Sometimes I’ll let her take charge and she’ll wake from 2-3 hrs to feed anyway.

My question: should I turn off the alarms and let her just sleep till she gets hungry even if that’s more then 3hrs ? She’s 2 months old and I nurse her (I believe that gives off less milk then formula leading to a less heavy sleep) ?
