How does a seed grow into a brother or sister? The non-fiction picture book 'Will it take long?' provides a clear answer to children's questions about pregnancy. Preschoolers who have a brother or sister are often very curious about what happens in their mother's belly. Science journalist Floor Bal, who received a Flag and Pennant from the Griffel jury for her book 'The whole soup zootje', tells us week by week how the baby in mom's belly develops, with a great sense of the experiences of young children. They get answers to questions such as: how big is the baby now? What can the child do? And of course the eternal key question also arises: will it take long? Using the beautiful pictures of illustrator Iris Deppe, Floor Bal gives toddlers a clear description of how a seed grows into a brother or sister. Strange bumps become arms, feet grow toes and people even pee in the amniotic fluid. 'Will it take long?' is a warm reading book in which children from different family compositions can recognize themselves. For expectant brothers and sisters from 4 years old.
