Asking for a friend – if a parent were to give money and supermarket gift cards to an adult child to buy food for herself and kids, knowing that the child buys treif and will likely buy treif with that money, is that an aveirah? In this case, the child has enough money with which to buy her own food but the parents would like to help out.

Additionally, if the parents were to buy a membership for the grandchildren to an entertainment place, knowing that they will mainly go on Shabbat, is that allowed? Again, the child has the money to be able to buy this on her own.

Thank you.
