Frequently asked

Is RelayBaby suitable from day one?
Yes. RelayBaby is designed for the realities of newborn nights, including cluster feeds, short naps, and frequent diapers. It works alongside your routine — it is not a medical device and does not provide medical advice.
Can I track left vs right side?
Yes, breastfeeding logs include side and timing, so you don't have to remember which side was last.
Does it stress me out with reminders?
RelayBaby is built to be calm. You decide which reminders to set, and the design avoids the noisy badges and upsells common in newborn apps.
