Such a lovely thought and so considerate of you. You can buy chocolates that do not contain gelatine or alcohol (pretty much all chocolates are suitable). Jelly sweet that are vegan are suitable often available in Asda or Tesco such as candy kittens or own brands. Since Ramadan is approaching you could add a box of dates in there too. Most supermarkets are selling them atm and even advent calenders. Hope that helps.
@Samina thank you so much for this response, omg the dates is such a good idea thank you!! X
I don’t think you could buy the wrong thing. The surprise sounds lovely x don’t over think it x
