Ah, Birch Tree is a trusted brand dito sa Pinas, kaya siguro okay lang for a 1-year-old, pero better to double-check the label if it's specifically formulated for toddlers or kung may any ingredients na hindi pa ready ang baby. Since nutrition and milk choices vary from baby to baby, I'd really suggest asking your pedia about it, they know your kiddo's needs best and can confirm if it's the right one for his age, lalo na kung may allergies or sensitivities siya.
