Eh, honestly at 1 year old, kalau dia makan varied diet dengan fruits, vegetables, and protein, sometimes tak perlu supplement pa, tapi I know some of my mum friends lebih tenang dengan multivitamin especially kalau anak picky eater. Best thing is check with your pediatrician first, dia tau best based on your child's diet and needs, some doctors recommend specific brands yang suitable for toddlers, ada yang say makanan je cukup pa. Every kid berbeza, so better get professional advice than guess-guess je!
