Question:
Regarding my previous question about din on a family after a death, again I was told that having a baby lifts the din?
Where can I read more about this?
Answer:
You can look in Nimukei Yosef Moed Katan 28a, who brings a Yerushalmi moed Katan 3-7 who says this "נולד בן זכר במשפחה נתרפה כל המשפחה". It is also brought in the Tur and Shulchan Aruch Y:D 394-4.
Best wishes
