Well kiddo, a galactogogue is a fancy word for something that can help mommies make more milk for their babies. You know how mommies have special milk in their breasts that they give to babies to help them grow big and strong? Well sometimes mommies don't make enough of that milk, and that's where a galactogogue can come in handy.
It's like magic helper medicine (but safe for babies!) that helps mommies make more milk. Galactogogues can be things like certain foods, herbs, or medicines that a mommy can take to help boost her milk supply.
It's kind of like watering a plant to help it grow big and strong. Just like how plants need water to grow, babies need milk to grow. Sometimes the milk supply needs a little help to keep up with how much the baby is drinking, and a galactogogue can do just that!
