Singing a lullaby to a baby in the womb could help them with speech development, a new study has found.
Researchers at the University of Helsinki had 12 women play Twinkle Twinkle Little Star to their babies five days a week for the final stages of their pregnancies. The brains of those babies reacted more strongly to the familiar tune when they were born, as well as four months later, when compared to 12 babies who didn't hear the song while in utero.
"These results show that babies are capable of learning at a very young age, and that the effects of the learning remain apparent in the brain for a long time," researcher Eino Partanen said.
The results are significant because studying the responses in the brain lets the researchers focus on the foundations of fetal memory, the study says.
The study was published in the journal PLoS ONE.
