Hey won't you need to be pregnant or a lil after birth to be able to breastfeed... or did i misunderstand something... ??
Some women can naturally lactate outside of pregnancy. For those that can't, there are hormonal medications that can induce the ability to lactate.
Moderate grossness warning: Even men are capable of lactating under certain circumstances. Hormone spikes during puberty or from hormonal medication can cause men to lactate.
