Young parents all over Belgium rely on Nutricia babyfoods every day. To support mums even before their baby is born, Duval Guillaume helped Nutricia create Baby Connection, an iPhone app designed to get dads more involved in the pregnancy.
Baby Connection works best when you use it as a couple. There is a mum version and a dad version, and everything each parent adds is automatically synced with their partner’s phone. The app can even transform two iPhones into one big screen.
A couples app that turns involvement into habit
The mechanism is simple and deliberate. Split the experience into two roles, then keep both roles in lockstep through syncing. Add a playful physical trick, two phones acting like one screen, to make “doing this together” feel tangible, not just promised.
In Belgian consumer brand building, support tools land best when they reduce friction for both parents and make the dad’s role practical, not symbolic.
Why it lands
This works because it shifts the conversation from “be more involved” to “here is exactly how”. Shared inputs, shared visibility, shared moments. The app design quietly nudges the couple into repeated check-ins, which is where involvement stops being intention and becomes routine.
Extractable takeaway: If you want two people to share responsibility, design the product so both can contribute in small ways, see each other’s contributions instantly, and feel like a team without extra coordination effort.
Launching an app with an experience, not a banner
The real question is how to make shared participation feel real before the baby arrives, not how to advertise another pregnancy app.
To launch Baby Connection, Duval Guillaume backed the app with a campaign designed to be as distinctive as the product itself, and to pull the idea into public conversation beyond the app store listing.
The stronger move is to market the shared behaviour the product enables, not just the app itself.
What pregnancy-support brands can borrow
- Design for the couple, not the individual. Two roles, one shared narrative.
- Make syncing the default. Shared visibility is the involvement mechanic.
- Add one physical “together” moment. A simple device interaction can signal partnership better than copy.
- Launch the product idea, not only the product. If the behaviour change is the point, market the behaviour.
