Well 'lactose' is the name of the sugar found in milk.The other names are: milk sugarand officially (IUPAC): β-D-galactopyranosyl-(1->4)-D-glucose

Lactose is a disaccharide that consists of β-D-galactose and β-D-glucose fragments bonded through a β1-4 glycosidic linkage. It's also a solid by the way.
The equation for the formation of alpha-D-lactose from beta-D-galactose and alpha-D-glucose involves the transfer of galactosyl group from beta-D-galactose to alpha-D-glucose, forming a glycosidic bond between the C1 of glucose and the C4 of galactose. This reaction is catalyzed by the enzyme lactose synthase.
Lactose-free varieties of milk provide the same nutrients as regular milk. The nutrients in an 8-oz. glass of nonfat, lactose-free milk include 8.3 g of protein; 12.5 g of sugars; 0.2 g of fat; 5 mg of cholesterol; 300 mg of calcium; 250 mg of phosphorus; 380 mg of potassium; 27 mg of magnesium; 150 micrograms of vitamin A; and 2.9 micrograms of vitamin D. The vitamin D, calcium, phosphorus and magnesium in lactose-free milk help support your bone health.
A) Bacteria in yogurt produce lactase B) The lactose content of yogurt is about one-half that of milk C) Yogurt is poorly tolerated in lactose-intolerant people D) There are only trace amounts of lactose present in yogurt
Lactase catalyzes the hydrolysis of lactose, a disaccharide found in milk, into its constituent monosaccharides, glucose and galactose. This enzymatic reaction allows for the digestion and absorption of lactose in the small intestine.
Lactose is classified as a disaccharide, which means it is made up of two sugar molecules (glucose and galactose) joined together. It is commonly found in dairy products and is a primary source of carbohydrate in milk.
Foods that contain lactose. You may not need to completely avoid foods and beverages that contain lactose —such as milk or milk products. If you avoid all milk and milk products, you may get less calcium and vitamin D than you need. People with lactose intolerance can handle different amounts of lactose.
Lactose in the diet
Lactose (also referred to as milk sugar) is a sugar which is found most notably in milk. Lactose makes up around 2-8% of milk (by weight). The name comes from the Latin word for milk, plus the -ose ending used to name sugars. Its systematic name is β-D-galactopyranosyl-(1↔4)α-D-glucopyranose.
For a lactose intolerant toddler, recommended dietary guidelines include avoiding dairy products with lactose, such as milk and cheese, and opting for lactose-free alternatives like lactose-free milk or dairy-free products. It is important to ensure the toddler gets enough calcium and vitamin D from sources like fortified non-dairy milk, leafy greens, and fortified cereals. Consulting a healthcare provider or dietitian for personalized guidance is recommended.
