YOU SAID:
My baby is due tomorrow for sandwiches
INTO JAPANESE
私の赤ちゃんは明日サンドイッチを食べる予定です
BACK INTO ENGLISH
my baby is going to eat a sandwich tomorrow
INTO JAPANESE
私の赤ちゃんは明日サンドイッチを食べるつもりです
BACK INTO ENGLISH
my baby is going to eat a sandwich tomorrow
That didn't even make that much sense in English.
