Is bilingual parenting good for my baby's development, and how do I start?

Bilingual exposure from birth is one of the greatest cognitive gifts you can give your child. Research consistently shows that bilingual children develop stronger executive function (attention, mental flexibility, working memory), and bilingualism does NOT cause language delays. Babies can distinguish all the world's language sounds until about 10 months, then specialize — so early exposure is ideal. Common approaches: one parent/one language (OPOL), where each parent consistently speaks a different language; minority language at home, majority language outside; or time-based separation (mornings in one language, afternoons in another). Consistency and quantity of exposure matter: each language needs at least 25–30% of the child's waking input to develop well. Don't worry about mixing — code-switching is normal and shows the child understands both grammars. Consult your pediatrician about language milestones, which are slightly different for bilingual children.
