You can't give honey to infants under one year of age.
You have to wait until a baby is at least 12 months old before you give them honey.
ーYou can't give honey to infants under one year of age.
「1歳未満の乳児にハチミツをあげちゃダメ。」
infant で「乳児」
under one year of age で「1歳未満」
ーYou have to wait until a baby is at least 12 months old before you give them honey.
「乳児が少なくとも12ヶ月になるまでハチミツをあげるのを待たなければいけない。」=「あげちゃダメ」とも言えますね。
baby で「赤ちゃん・乳児」
at least 「少なくとも」
