What to Eat When You’re Expecting

Every parent wants to give their child the best start in life. During the first 1,000 days—starting from pregnancy and extending through toddlerhood—children’s brains grow more rapidly than at any other time. This period calls for high-quality nutrition, and dairy is key to supporting strong brain, bone, and body development during these critical early years.
