Feeding bottle

Can I reuse same bottle after every feeding? Malakas kase tulo ng milk ko so advise ni pedia na mag bottle feeding nalang since lagi nasasamid si lo. So sa bottle 2ounce lang lagi nilalagay ko. Okay lang ba gamitin uli yung bottle after or kelangan bago and sanitized ang bottle kesa sa magrefill sa gamit na bottle#1stimemom #firstbaby #advicepls ? #firstbaby
