Hi there! From what I hear, Columbia Asia Hospital Klang does quite comprehensive antenatal classes, a few mums I know went and said the instructors were really helpful with breastfeeding tips and what to expect during labour, so that's worth looking into. Some of the classes are held at Wyndham Hotel in Klang as well, which makes it convenient. I'd suggest calling the hospital directly to ask about their current schedule and whether they offer specialised lactation sessions, as they do seem to run them regularly. All the best with your preparations!
