Honestly, I'd say start with your own delivery hospital first, places like Mount Alvernia have their own Parentcraft Centre and the classes tend to be more affordable, plus the info is tailored to how they do things there, which is quite practical. My friend went to Thomson Medical and said they also run antenatal classes that cover a lot of ground, so it's worth checking with them directly if that's where you're delivering. That said, some mums feel hospital classes are a bit rushed and prefer smaller private classes where you get more personal attention, really depends on what you're looking for. I'd honestly call a few places, ask how many couples per session, and see which vibe suits you, because the quality can vary quite a bit even within the same hospital depending on the instructor.
