Who Will My Baby Look Like — Me or the Father?
This page is about resemblance: which parent a child ends up favouring, why it shifts over time, and what an AI blend can honestly show you.
The short answer
Neither parent has the advantage. Each of you contributes half your child’s DNA, and the half that gets passed on is shuffled fresh every time. Resemblance is the visible outcome of that shuffle, so it lands differently for every child — which is why two siblings with the same parents can favour opposite sides of the family.
The popular idea that newborns are born looking like their father has been tested repeatedly and has not held up: the studies that have looked at it since the 1990s mostly find no consistent bias either way. What does happen is that relatives look for the father’s features and say so out loud, which makes the pattern feel real. Resemblance also drifts through the first couple of years as the face loses its newborn roundness, so the parent a baby favours at six weeks is often not the one they favour at three.
An AI blend cannot tell you which of you will win. What it can do is show you the midpoint — a plausible face built from both of your photos — so you can see which of your features and which of your partner’s survive being combined. FaceCast does that from two photos in about a minute and returns a boy and a girl version. If what you actually want is a picture of the future baby rather than an answer about resemblance, the /what-will-my-baby-look-like/ page covers that side.

Compare your features side by side
Add a photo of each parent
Front-facing, evenly lit, whole face visible. One face per photo — the model has to read both sets of features cleanly to blend them.
Generate the blend
The AI builds a new face weighted between the two of you rather than pasting either one on top of the other.
Look for what carried through
Compare the result against both source photos: the eye shape, nose bridge and jaw usually make it obvious which parent the blend leans towards.
Why a baby ends up favouring one parent
A few traits follow patterns simple enough to reason about. Darker eyes and darker hair are usually dominant, so if one parent has brown eyes and the other blue, brown is the likelier outcome — though two brown-eyed parents can still have a blue-eyed child if both carry the recessive variant. Traits like these are where a parent visibly "wins", and they are a small minority of what you see in a face.
Everything else — the shape of the nose, the set of the eyes, the width of the jaw, the way a smile sits — is polygenic. Dozens of genes contribute to each one, and they do not sort as a package, which is why a child routinely gets one parent’s eyes and the other parent’s mouth. Overall resemblance is really the sum of a few dozen independent coin flips, and that is exactly why it cannot be called in advance.
What shifts the answer over time
Newborn faces are still forming
Swelling from birth, a rounder skull and undeveloped nasal structure make most newborns resemble each other more than either parent.
The first two years change a lot
As baby fat recedes and the nose and jaw develop, the parent a child favours can flip entirely.
Observers are not neutral
Family members tend to look for the father’s features and announce them, which inflates how often "just like dad" gets recorded.
Siblings diverge
Each child gets a different shuffle of the same two genomes, so one can favour you and the next your partner.
Frequently asked questions
Who will my baby look like, me or the father?+
There is no way to know in advance. You each pass on half the DNA, but which features become visible depends on a combination that has not happened yet. Some individual traits, like dark eyes over light, are more predictable — overall resemblance is not.
Is it true that babies look more like their father at birth?+
It is a persistent belief that the research does not support. Studies since the 1990s have mostly found no consistent lean towards either parent. The impression is largely down to relatives actively looking for the father in a newborn’s face and saying so.
How is this different from the "what will my baby look like" page?+
This page answers a resemblance question — which parent your child will favour, and why that changes as they grow. The /what-will-my-baby-look-like/ page is about appearance: it walks through generating the face itself from your two photos. Same app, two different questions, and most people eventually want both.
Can AI tell me which parent my baby will resemble?+
No, and be wary of any tool that claims otherwise. FaceCast blends both parents’ features into a plausible face rather than weighting the result towards one of you. What it shows you is the midpoint, not a prediction of who wins.
Will our second child look like the first?+
Not necessarily. Each child inherits a different random half from each parent, so siblings often favour different sides of the family despite having exactly the same parents.
Is there a free way to see the blend?+
Yes. FaceCast is free to download on iOS and Android and includes a free trial, so you can generate a blended face — boy and girl versions — before deciding on any optional in-app purchase.
Are our photos kept private?+
Your photos are processed securely to create your images and are not shared with third parties.
