Wa'alaikum assalam! Hmm susah jugak cari CL yang betul-betul boleh dipercaya kan, tapi a few of us dari area Petaling Jaya ni biasa tanya through word-of-mouth, either from mum friends yang dah try atau dari neighbourhood WhatsApp groups yang ada referrals. I'd suggest join the PJ parents Facebook groups or even ask in your building WhatsApp, usually parents kat situ boleh recommend orang yang dah tested by people we know la, which is safer than random. My one friend swears by checking references dulu and do a trial period, maybe half day first to see how your kids gel with them. Good luck finding someone reliable!
