I really feel you on this, the P1 registration period can feel so overwhelming and you just want to connect with other parents going through the same thing. I don't have a specific link for Lian Hua's group chat, but your best bet is probably to ask directly at the school's general office as they sometimes help link new parents up. You can also try searching "Lian Hua Primary P1 2024" in Facebook Groups, as quite a few schools have parent communities set up there by other mums and dads lah. Hope you find your people soon, it really helps to have that support network before school starts.
