I had to get passport photos when my baby was only a week and a half old - I tried a few different places, but then they recommended doing it at home on a white sheet and just getting them to develop it and size it properly and everything. It worked SO much better for us, because at home, we could just do it when she was alert and looking around - because it's HARD to get a newborn looking straight on and eyes open and mouth closed and "neutral expression"... but we applied for the Aussie passport last week and everything was fine. So you can try that if you like, it depends on how old and alert your baby is and everything...
