Your baby's becoming more sensitive to sound as the network of nerves in her ears develops. If dad talks to her now, she might learn to recognise his voice. The more she hears it, the more likely she is to find it soothing after she's born. If he feels strange just talking to the baby, he can read the newspaper or a book out loud.
E que bem se notou o quão sensível a Maria está ao som exterior no Musical do Rei Leão em Londres! Até tive pena dela, apanhou cada susto! Mas minha querida, valeu muito a pena :-)
