Sleep question-help!

I’m trying to get my LO on a schedule but struggling. I’ve read babywise and am very loosely following that. She is 7 weeks old and is still waking every 2 hours at night. She eats every 2 hours during the day so I’ve been assuming she is hungry every 2 hours at night. Should I try to soothe her with a pacifier instead of nursing her? I don’t want her to be hungry but I don’t know how how to extend her sleeping either!

Do you have any recommendations?

TIA 😱 tired mommy!
