My little girl is nine months and she takes the pacifier when she's falling asleep and has it when we put her down but then when she fall's asleep it falls out and she's fine. Is he okay once he's asleep and it falls out?? I'd give him the paci to fall asleep, but him down and then it'll fall out when he's in a deep sleep. Make it easy on you, wait til he's older to go through it ;0)
We'll be in the same boat one day, screaming toddler wants paci. Good Luck!
