You need to renew your passport first.
Congratulations on the baby. You also need to inform NDVO immediately that you have a new baby. You will need to add her to your application, which involves updating all your paperwork, obtaining a birth certificate and passport for your baby, and showing more POF for a larger family. Your application will be on hold until you provide all the necessary paperwork and NDVO also determines that they are ready to issue a visa for your baby. There is no other option.
If you already got PPR it's almost 100% that you will get it again after adding your baby to the application, so all this costs you is some time and money, but you must do it.
