A goy hired to work for you for the year must not be allowed to eat his own chometz in your house — it looks suspicious. (MB14)
Whenever you give money to a goy on Pesach do not tell him to go buy chometz with it — even though he is buying it for himself, it looks as if he is your shaliach. (MB15)
The following is the list in descending order of preference for a child who needs to be fed chometz for his health on Pesach: (1) Have a non-Jew feed the child in the non-Jew’s house for free. (2) Promise the non-Jew payment after Pesach. (3) Tell the goy to take home any uneaten chometz and bring it back for the next feeding. (4) The goy leaves his chometz at the Jew’s house and the Jew explicitly states he does not wish to acquire it. (5) An older child feeds the ill child. (6) Store the chometz food in the room with the other sold chometz. (7) Make a mechitza ten tefachim high around the chometz or turn a container over on the chometz. (MB18)
If the child urgently needs to be fed (sakana), do not make any of the above considerations if they will delay the feeding in any way. (MB18)
