Till she is almost 15 months. She definitely sleeps better without the paci now. You can try to cut the tip of the paci first. They won't get the same satisfaction from sucking and will lose interest in the paci. However, your baby is only six months and don't know if he will understand that paci is broken. Thatswhat we told my daughter and she understood it and was sad for couple days, but then got over it.
