Does giving pacifiers to breastfed babies will result into nipple confusion?

Depends what age from my experience. When they're under 3 months and still learning to latch on, it could be confusing but as they get older I think its ok and pacifiers can be a very soothing remedy. I'd be careful on being over reliant on pacifiers though. Some kids get used to only sleeping with the pacifier and the minute it falls out of their mouth, they wake up. But it can also be super useful to soothe babies and work as a comforter.
