To my knowledge there is only one way. Across the placenta and into the foetus. Everything taken into mothers body will pass across the placenta, around the system of the foetus and even returning waste back across the placenta through the magic of Osmosis.
Carbon dioxide and other such waste gases diffuse from the foetus and across the placenta into the mother's blood. Urea (excretory product) also diffuses into the mother's blood. (The substances in bold will answer question).
Harmful substances can reach the placenta through various pathways, primarily via maternal circulation. Substances such as drugs, alcohol, environmental toxins, and certain infections can cross the placental barrier, often due to their small molecular size or lipid solubility. Additionally, maternal health conditions or behaviors, such as smoking, can further elevate the levels of these harmful substances in the bloodstream, ultimately exposing the developing fetus. This transfer can have detrimental effects on fetal development and health.
An unborn baby is referred to as a fetus, or foetus.

The duration of Foetus - film - is 1.7 hours.

The fetus receives oxygen and nourishment from the placenta via the umbilical cord. Waste and carbon dioxide return to the placenta via the umbilical cord.
External preasure on abdomen does affect the foetus.
A growing fetus receives oxygen and nutrients through the mother's blood supply. The placenta acts as a bridge between the mother and the fetus, allowing for the exchange of oxygen, nutrients, and waste products. The umbilical cord connects the fetus to the placenta, providing a pathway for these essential substances to reach the developing baby.
