Built for two
A baby tracker made for two parents.
Most trackers are built for one person logging alone. Milk Monster is built for the people raising them together — one calm, shared log that every caregiver sees update live.
Sound familiar?
“Wait — did you already feed her?”
Whispered across a dark room at 3am. When two people are caring for one baby, the hardest part isn’t the logging — it’s staying on the same page. A tracker that only lives on one phone can’t fix that. One that everyone shares, live, can.
How shared logging works
Three steps to one live log.
Create your household
One of you sets up the baby and a household — it takes a few seconds.
Invite your partner (or grandma, or the nanny)
Send a simple invite link. Each caregiver joins with their own account — no shared password.
Log together, live
Anyone logs a feed, a nap, a diaper — and it appears on everyone’s phone a second or two later, with their name on it.
Why two parents love it
- Always in sync. Log on one phone, it’s on the other in a second or two — no refreshing, no shared password.
- Who-logged-it on every entry. You can always see who fed the baby last, and when.
- Calm and one-tap. Designed for tired hands at 3am — even from your Lock Screen, without unlocking.
- The whole care team. Add a grandparent or a nanny, each with their own role.
- Private by design. No ads, no third-party trackers, and we never sell your data.
Common questions
Sharing a tracker with your partner
What is Milk Monster?
Milk Monster is a calm, shared baby tracker for iOS, built for two parents. Each caregiver logs in with their own account and sees one live, shared record — log a feed, nap, diaper or pumping session on one phone and it appears on everyone else’s in a second or two, tagged with who logged it. It’s free to start, with Premium adding real-time sharing across every caregiver, your full history, and weekly trends.
How do two parents share a baby tracker?
With Milk Monster, one parent creates a household and invites the other with a link. Each parent logs in with their own account and sees the same live record — when one logs a feed, it shows up on the other’s phone in a second or two, tagged with who logged it. There’s no shared password and nothing to sync manually.
Does each parent need to install the app?
Yes — and that’s what makes it work. Each caregiver has their own account on their own phone, all looking at one shared log. That’s how you always know who fed the baby last and when, without texting each other to ask.
Can grandparents or a nanny join too?
Absolutely. You can invite anyone who helps care for your baby — a grandparent, a night nurse, a nanny — each with their own role. Everyone sees the same live log, so the whole care team stays in sync.
Is a shared baby tracker free?
Milk Monster is free to start with full one-tap logging for one caregiver. Real-time sharing across every caregiver is part of Premium ($9.99/month or $59.99/year) — and every new account’s first week of Premium is free, automatically — because shared, live logging is the heart of what the app does.
What can you track together?
Breastfeeding (with sides and duration), bottles split between expressed and formula, sleep, diapers, pumping with per-side totals, temperature and medicine, plus growth charts and a milestone journal. It all lives in one calm, shared log.
