Hi, my bb is 7 days old. Fully latch on demand. He tend to be more cranky at night, any advice should I start giving him pacifier? Will it cause nipple confusion?

I started giving baby pacifier at about one month. No nipple confusion. She's now 4 months old and needs to latch or have a pacifier to fall off to sleep. Once she's asleep we remove the pacifier from her mouth. I personally believe that pacifier use is okay if breastfeeding is going very well and has been established. This usually happens in the third to fourth week.
