I did this course with my mothers group and our partners, and I would highly recommend it.
The course was perfect for new parents. It was very practical, and hands on. There was just the right amount of information - enough to feel prepared, but not so much that you have no hope of actually remembering what to do in a stressful situation. Instead of "teaching to a curriculum" to get a certificate at the end, the course tells you what you'll actually need to do and, importantly, what you'll remember to do. It is delivered in a really digestible and dynamic way - it just felt like a friend having a chat, not like a boring lecture.
Peta was also really easy to deal with to organise the course, and it was great to be able to split the four hours of content over two sessions (for no extra cost) to avoid information overload of doing it all in one go.

Approximate cost: $80 for 4h
