If the item is for everyday use, you can say「明日から持たせます」(asu kara motasemasu), meaning “I’ll have my child start bringing it tomorrow”. On the other hand, if the item is for one-time use only, 「明日、持たせます」 (asu motasemasu), or “I’ll have my child bring it tomorrow,” can be used.
You may choose whether or not you wish to include the optional "What you will do” section. You may simply reply to the teacher's message with the one-word statement「わかりました」 (wakarimashita), or “OK”.
