Will using two names confuse my baby

Hello mummies, I call my baby by his English name, while my mother-in-law calls him by his Chinese nickname (also because she can't pronounce his English name). My mother-in-law is the one mostly taking care of him while I’m at work. I’m worried that having two names might confuse him, and he might ended up not respond to his name by a certain age. Mummies do you all call your baby by both real name or nickname? Which name did your baby end up responding to? Any advice for my situation? Should i just follow my MIL and call him by his nickname
