I hope you sorted this! Maternity leave is in most agreements- generally a certain amount of unpaid leave. Also look at the return to work policies. Ie lactation breaks if required, part time hours etc

Centre link will give you the forms for their parental leave but you will still need to apply through your work. I looked up the companies policy and I had to write a request for the leave. Try that and see how you go but keep records of all of your correspondence with them incase you need it later.
