I really feel you on this, finding the right playgroup can feel so overwhelming with so many options out there. My friend tried a few with her little one and she said the ones run through community centres tend to be really welcoming and affordable, good for kids to mix around with others their age. You might also want to check what is available near your area through the PAP Community Foundation or My First Skool, as they sometimes have trial sessions. It is worth just dropping by and getting a feel for the teachers and environment before committing lah.
