Can a One-Week-Old Baby Smile?

At just one week old, a baby typically does not smile in the way we understand a smile to be. Newborns are still adjusting to their surroundings, and what might appear to be a smile is often just a reflex or a response to various stimuli. Genuine social smiling usually starts to emerge around the six to eight week mark as infants become more aware of their environment and begin to interact with others.
