Parent baby record books to go digital

New parents will no longer need to keep a paper baby book recording their child's development, under changes announced in the federal budget.

The government is committing $5 million over two years to develop a national digital baby book.

This will replace the existing state and territory hard copy books that document a child's health records.

The budget released on Tuesday also includes $3 million to develop a new guide for would-be parents on how to stay healthy during pregnancy.

And every Australian mother will be able to be vaccinated against whooping cough for free, after the government found $39.5 million to list the vaccine as part of the national immunisation program.
