Re: 2 wk old spitting up but still hungry - comfort nursing?
Spitting up that happens without evidence of pain = laundry issue. Don't worry about it, and don't feel like it's a problem that you need to solve.
Just FYI: pacifier use is discouraged until 3-4 weeks, or until breastfeeding is well-established. At 2 weeks your baby is still just beginning to master the art of nursing, and your milk supply is trying to find the right level. So it's best to meet baby's suckling needs with the breast right now, as nature intended.
