It's hard to pinpoint a specific age when kids "love" their parents because their understanding of love evolves with their development.
Babies and toddlers express their love through physical closeness, smiles, and babbles. They rely on their parents for basic needs and security.
Preschoolers begin to understand that love is a special feeling and express it through words, gestures, and gifts. They may say "I love you" or draw pictures for their parents.
School-aged children develop a more complex understanding of love and may express it through acts of service, sharing, and empathy. They start to appreciate their parents' sacrifices and guidance.
Teenagers often experience a range of emotions, including strong feelings of love and appreciation for their parents, even if they don't always show it outwardly.
While the expression of love changes over time, children generally feel a deep sense of attachment and affection for their parents from a very young age.
