Wa'alaikumassalam! Sayang, I haven't personally tried DBM Batu Caves, tapi a few of my mum friends nearby area recommend asking in the local Batu Caves parent groups or WhatsApp community, usually they're super helpful with doctor reviews sebab everyone knows each other! Maybe try asking in the KL/Selangor mum forums juga, banyak orang ada experience dengan clinics dekat situ. Goodluck finding info, hope someone replies to you with their experience!
