I give her the boob whenever she wants it.
At night I don't turn on any lights and I don't talk to her or give any eye contact. I feed her to sleep at night lying down and put her straight back into her bed when she's done. She's 11 weeks now and between 9pm - 7am wakes once or twice for a feed only.
I agree with everyone else above - do what works for you! Theres no right or wrong way. If something works now, do it. If it stops working, try something new.
If your worried about knowing if she is really hungry, i recommend googling dunstan baby language. In the early days that helped me distinguish hungry/tired/burp me. Now I know most of her cries and sometimes I offer boob for comfort only when she needs it.
I also found the wonder weeks app fantastic. Explains why a bubs might be 'unsettled' and I love knowing the extra crying is a normal developmental thing and that extra comforting is needed to get her through.
Hope this wasn't too rambled. :/
