Here's why:
* Genetics: Babies inherit half of their DNA from their mother and half from their father. This means they get a blend of traits from both parents. Some traits might be more dominant, so you might see more resemblance to one parent than the other.
* Individual Variation: Every person is unique, and babies are no exception. Even with the same parents, siblings can look very different. This is due to the way genes are shuffled and recombined during conception.
It's impossible to predict exactly how a baby will look. Sometimes, it might seem like a baby looks more like one parent, especially in the first few days or weeks. However, features can change as the baby grows and develops.
Fun fact: There's actually a scientific field called "familial resemblance" that studies how people resemble their relatives!
