Advice on how your baby can roll over

Hi mga mommies! I'm a first time mom and I have a 3 month old baby who now weighs 9.2 kg. I know that every baby is different when it comes to reaching their milestone but do you guys have any advice kung paano agad tumaob ang baby kahit na ganyan kabigat yung katawan ni baby? I would appreciate if you could share your experiences and expertise. Thank you ?
