The arrival of a baby is a time of intense change, not only for the child but also for the relationship between the adults. One of the most common sources of tension at this time is the question: who is responsible for what? Is there a natural division of roles? Should mum do more? Where does dad fit into all of this?
Modern science provides surprisingly consistent answers to these questions while also freeing parents from many myths.
Biology matters, but it does not determine everything
Some biological asymmetries can occur early in a child's life:
- The mother goes through pregnancy and birth,
- breastfeeds frequently,
- her body produces hormones associated with caregiving, such as oxytocin.
In the first few weeks, the mother is often more immersed in day-to-day care. The source says that research suggests she may respond more quickly to the baby's subtle cues. Its central point, however, is that the quality of care is shaped by experience and involvement rather than biology alone. A father who takes an active role in care from the outset can develop the same skills quickly.
A father is not a helper; he is an equal carer. One of the greatest linguistic and cultural mistakes is saying that Dad helps. You can help someone who is responsible. In reality, both parents are responsible.
Attachment research shows that a baby can form a strong bond with both their mother and their father. What is more:
- children benefit from having two engaged carers,
- an actively involved father can support emotional and social development,
- his presence reduces the mother’s stress levels (which indirectly affects the child).
Differences Between Mothers and Fathers
In practice, many parents notice that they care for their child in different ways. Research confirms this.
It is often observed that:
- mothers soothe the child and regulate their emotions more often,
- fathers initiate play and stimulation more often.
This does not mean that families must follow one pattern. Different caregiving styles can broaden a child's experiences and support development, helping them encounter both security and opportunities to explore the world.
The Invisible Work — A Major Source of Tension
Many conflicts are not about who changes or bathes the baby, but about something less visible:
- planning, such as arranging vaccinations and deciding what to buy,
- remembering whether there are nappies and whether the child has eaten,
- emotional vigilance (whether everything is 'all right').
this is known as the mental load and emotional labour.
Research indicates that this mental load often falls mainly on mothers, even when practical tasks are shared. A fair division therefore involves not only doing tasks but also sharing the planning, remembering and monitoring behind them.
So, is there an ideal division of responsibilities? No. And that is good news.
There is no single model that works for everyone. There are, however, principles that support the wellbeing of both the child and the parents:
- Flexibility
The division of responsibilities changes over time: needs are different during the postpartum period and different again after a few months.
- Reciprocity
Both parents are entitled to feel tired and to rest.
- Visibility of work
Appreciating what the other person does, including the things that go unseen.
- Communication
Regular conversations reduce mounting tension.
What Really Matters Most to a Baby?
From a developmental-psychology perspective, a child needs:
- caregivers who respond to the child’s needs,
- emotional stability,
- a relationship in which adults cooperate rather than compete.
the strongest predictor of a child's wellbeing it is not about who does how much, but about the quality of the relationship between the parents. Instead of seeking perfection, it is worth building a collaborative approach:
- treat each other as a team rather than partners keeping score,
- allow yourselves to have different ways of being with the child,
- speak openly about your needs,
- remember that tiredness changes your perspective; this is normal.
Division of Responsibilities with an infant is neither predetermined nor fixed once and for all. It is a process that requires:
- mindfulness,
- conversations,
- a willingness to change.
Mum and dad do not have to do everything in the same way. Nor do they have to divide everything equally. What matters most is that they do it together. For a child, the most valuable thing is not who got up during the night, but growing up within a relationship built on closeness, cooperation and security.
