When a new baby is on the way, siblings-to-be have lots of feelings and plenty of questions.But whether they're impatient, curious or a little worried, this friendly and reassuring guide explains each step of the pregnancy journey and helps little ones feel involved and excited.With a month-by-month approach that compares the size of the growing baby to something familiar to the young reader, such as a speck of sand at the seaside or an egg, readers also find out about how Baby is developing, from when the heart might first beat to when they'll be able to feel it kick.The book also includes information about how life might change once Baby arrives, and how exciting it will be to have a new baby brother or sister.
