Pacifier

First time mom with a 15 month old son & currently 5.5 months pregnant. My son has used a pacifier since he was an infant. He usually uses it while napping and he goes to to bed with it even though he spits it out about 20 minutes after falling asleep. It’s usually attached to his clothing during the day and he uses it when he feels like it or to soothe himself. I’m curious as to when to start taking it away. I know some moms never used one while others have 2 1/2 yr olds that still have one. I know there’s no right or wrong just curious on what has worked for others. I’m due in August so I’m wondering if taking the pacifier away now before baby comes if that will backfire since he will see the new baby using one. Thoughts?
