Dear mummies, How do u stop your lo from latching to sleep?

Those experienced mummies, they said have to let others to coax your child to sleep. I am still trying to work it out with my LO as i don't have anyone else to coax him. I will tell LO. ok, enough to latching, then i will pat him to sleep. If really can't i will latch him a little more. before unlatching him and continue to pat.
