Honestly tak sure lah, I haven't tried that combination myself, a few of my mum friends pakai Dr Brown but dengan puting dia punya sendiri je. NUK latex teats are wider at the base so might be tricky to fit snug on Dr Brown bottles, tapi best you check the bottle neck size first since different brands punya different sizes. Maybe try asking at a baby shop or the NUK customer service to confirm compatibility before you beli? Better safe than sorry lah, kan!
