Every baby is unique and latches differently. This pack contains a slow and medium flow nipple to help you find the perfect flow for your baby. Signs it's too fast... gulping, coughing or gagging, refusing to feed, or excess milk dripping out of baby's mouth. Or too slow... if baby takes over 20 minutes to finish a feed, tugs at the nipple or falls asleep while feeding, they may need a faster flow. These bottles are compatible with natural start and closer to nature nipples. Advanced anti-colic nipples are not compatible. Food safe. tommeetippee.com.
