breastfeeding...

i will exclusively be breastfeeding my rainbow baby hes due any day now... my question is most people said dont give him a pacifier till u get home or they wont breastfeed idk why lol my 1st son never took the pacifier or bottle... but having a toddler and a newborn im hoping this baby takes it to help it soothe so there not both crying anyways my question is can i give him a pacifier in the hospital after hes born and how long did u give ur child a pacifier before taking it away...
