Built for newborn nights.

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.
