Now my son very attached to pacifier. He cries when i took it especially when he bored or sleepy. So worry about it.. is it ok to let him use it for prolonged time?

When he is active, do not give him. So he will not relay on it like even talk also want bite it. I only give to soothe her to sleep or when she is in pain during teething period, so easier to wean off too. As i'm Not sure how old is ur LO now, if he is already older than 1-2 years old plus, i will suggest using a force weaning off on him. (My fren tried my method and after a few day he will stop, and they avoid walking pass pacifier section so not to remind him or when he talk about it, they change topic.) Make sure most of his teeth is grown, so u won't get much of the teething cranky.
