GAW, he specifically wanted me to nurse for the health benefits of the baby. Formula is an adequate substitute, but not really the same thing. I’m not sure what halacha would require.
Kasha, there are plenty of issues that are not really halachic and just about every day life. And then there are halachic things – do you require your wife to wash your feet? You are allowed to technically. Would you beat her (or have beis din beat her) until she washed your feet if she didn’t want to?
