How do I handle grandparents or extended family who undermine my parenting rules?

Conflicting parenting styles across generations are one of the most common family stressors. Start by assuming good intent — grandparents usually act out of love, not defiance. Choose your battles: some rule-bending at Grandma's house (extra sweets, later bedtimes) is harmless, but safety rules (car seats, sleep position, supervision) are non-negotiable. Have calm, private conversations using 'I' statements: 'We've chosen to handle discipline this way because...' Share articles from your pediatrician to support your position. If boundaries are repeatedly ignored, you may need to limit unsupervised visits for a period. Consult your pediatrician for evidence-based resources you can share with extended family.
