Bodily Autonomy is a right for consenting adults, not children.

Just to clarify: the right to bodily autonomy never has meant, nor should it mean, that people have the right to get whatever prescription, medical procedure or surgery they want from doctors just by demanding them. Medical practitioners have their rights too - and used to be, most were still bound by codes of ethics and evidence-based medicine.

Also, even societies that put great stock in individual civil liberties and privacy still put checks on the bodily autonomy of adults. In many jurisdictions, abortion is limited to a certain time in pregnancy, and to certain dire situations beyond that. Surrogacy is restricted by law in most countries/states, and banned outright in a growing number of them. Most jurisdictions make it illegal for adults to buy or hold drugs like opium, heroin and meth even if they are just for your own personal use. Most jurisdictions also have put in place laws limiting prostitution.

There's always a balancing act between the personal bodily autonomy of individuals and what's best for others and the larger society. Used to be, people in countries like the US had an automatic right to smoke cigarettes any place they wanted to. People smoked pretty much everywhere - at home, in offices and other work places, in restaurants, clubs, bars, theaters, airplanes, concert halls, sports stadiums, trains, elevators, waiting rooms, doctor's offices, hospital cafeterias, lobbies and waiting rooms - even in hospital patient rooms. It was very difficult to find smoke-free environments.

But after more and more research came out documenting the negative effects of smoking on smokers as well as of "second hand smoke" on people who didn't smoke, municipalities gradually put in place new laws restricting smoking in public and shared spaces. First, cig smoking was confined to certain sections of restaurants, bars and movie theaters - and gradually it was banned outright. Similarly, in offices, office buildings and other work places, smoking was initially restricted to certain areas - but then employers and entire buildings banned it completely. The dramatic changes in law and policy were the result of a sea-change in the public perception of how far individuals' right to bodily autonomy should go.

Also, many people think it's reasonable and best for adults to restrict their own bodily autonomy in certain situations, such as when TTC, pregnant, breastfeeding, raising children, caring for the sick and elderly, serving in positions of responsibility, operating a motor vehicle, driving a plane or trains. We have laws that say every adult has the right to try to obtain a driver's license, but even amongst licensed drivers no one has a right to drive while drunk, stoned or tripping.

In other circumstances, it's customary for adults to voluntarily restrict their bodily autonomy rights. For example, in most jurisdictions, women are not required by law to abstain from alcohol, recreational drugs, caffeine and a host of other substances when TTC, pregnant and breastfeeding - but the majority of women abstain from these anyway. Similarly, lots of people restrict their own right to bodily autonomy coz they think that doing so will be of benefit to loved ones and others they care about.
