Pacifiers

Hey! My daughter is a week old as of yesterday and I've started using a pacifier for when she goes to sleep, if not she will wake up wanting to breastfeed for a couple seconds before falling asleep again. My question is, I know this isn't recommended until she's a few weeks older, but has anyone not had a problem with starting this early? I only use it at night time, not during the day. TIA :)
