Weaning tips - help

Hi, I need tips for weaning currently my girl latch to sleep in terms of school she is drinking dutch lady chocolate milk - ps she dislike fm or normal milk taste tried and tested. She is already 26 mths hence the reason why it hurts too as she suck deeply. Maybe now she latch due to the night routine, i didn’t want to introduce bottle as I’m scared the weaning would be difficult. Please help, she currently still awake at nights to latch due to the routine. How to explain to my husband too? As my girl latch then will always ask for more but she already latch if I didn’t give she will cry murder #tiredmama
