Parent Tips

• Talk, read, and sing to your baby often. These moments help with bonding and early language skills.
• Give your baby plenty of supervised tummy time to strengthen neck, arm, and shoulder muscles.
• Encourage play by letting your baby explore different textures and colorful toys.
• Smile, make faces, and copy the sounds your baby makes—it builds communication and confidence.
• Spend time cuddling, holding, and comforting your baby. This helps them feel safe and loved.
• Keep a regular routine for sleep and feeding. Babies feel more secure when they know what to expect.
• Avoid screens during playtime. Focused attention helps your baby feel connected and supported.
• Always place your baby on their back to sleep on a firm, flat surface without pillows or loose blankets.
• Feed only breast milk or formula for the first six months unless your doctor advises otherwise.
• Never shake your baby. If you feel overwhelmed, place them safely in their crib and take a moment to breathe before returning.
