Breastfeeding During Pregnancy

Is there any reason / obligation to stop breastfeeding when one becomes pregnant? I would be happy to receive a source. {P.S. I already sent this question more than a month ago and did not receive a response — perhaps because NetFree blocks it?!} Thank you very much.

Shalom u’vrachah.

There is no such obligation.

However, the reality is that the milk supply decreases, and it is not sufficient to satisfy the nursing child. In addition, its quality declines, and it is no longer beneficial for the nursling.

Yevamot 42a:
It was taught in a baraita: A man may not marry a woman who is pregnant from another man, nor a woman who is nursing another man’s child; and if he married her, he must divorce her and may never remarry her, etc., lest she become pregnant, her milk become spoiled, and he thereby kill the child.

Rashi, Yevamot 42b:
“And if she marries, perhaps she will become pregnant” — after giving birth, and her milk will become spoiled for him, and she will kill her son through hunger.
[Although according to Rambam’s explanation, there is no proof from there.]

P.S. Your question did not reach us until today, and in our system it is not supposed to be blocked.
