baby can only hear from 18weeks onwards, so hubby read to him from then on. we read bedtime stories to him and sing lullaby occasionally. reading to babies can make him/her familiar with the parents voice thus can bond better and soothe the baby once he/she is born.
i dont't on music cos dont't want baby get used to it, read that music can help baby sleep better before and after born, but can get dependent on it. but i know some mommies on slow music or instrumental music for their babies.
