4 month old sleep training

hi! my daughter also turn 4months 2 weeks ago and is fully breastfed. my friend says, sleep training rarely works on fully direct latch babies 😅 some times they sleep through the night sometimes when its the cluster feeding period they will latch sometimes every hour. i tried sleep training my baby, but she wont sleep without me beside her cause she comfort latch to sleep. she dont take pacifier too. so i just gave up and let her be a baby 😂

my friend’s 10 month old still wakes up every 2-3h to feed 😅😅
