Night weaning

My 3+mo baby, around 6kg, is still waking 3-4 times a night to latch. I can tell sometimes it's just for comfort because she only latches for 5 mins before falling back asleep and doesn't suck very hard. Is it safe to start weaning her off the feeds at the age or do I need to wait till she's older? I cannot force her to drink more in the day, she will gag if I insist. She also doesn't take pacifier, we tried various brands and shapes but she rejected all.
