The sessions are free and led by experienced practitioners at KKH, so there's really not much to lose by joining, they cover things like introducing new foods and building positive mealtime habits, which are genuinely useful for first-time mums. That said, some mums find the general tips are things you can pick up from a good paediatrician visit too, so it depends on how hands-on you want to be with the guidance. I'd say if you have the time slot available, go for it, better to have the information and not need it than the other way around.
