The early stages of pregnancy are most vulnerable to the effects of alcohol. - Guidelines from health organizations recommend abstaining from alcohol during pregnancy, especially in the first 3 months, due to risks of harm. The early sensitive period means alcohol should also be avoided before realizing one is pregnant. - For women with problematic drinking, reducing alcohol intake or abstaining is advised, as they will need support to do so given fears of judgment over the health of their baby.
