Make, Xtianity is half Jewish. Is it also holy?
ZD, on the contrary, that day was as dark for Am Yisrael as the day on which the golden calf was made.
Yosef,
1. It depends on the person. If he needs the language for parnassa he might get a heter.
4. My experience is that kids (and adults) do mix languages but also know how to speak in one language.Some kids even speak each language with the proper accent. What is a problem is when the parents speak to the kid in different languages from the get-go as absorbing both at the same time is too difficult for a toddler.
