i once heard this and i think it’s beautiful:
“when it come to having children, don’t see if there’s room in your house. see if there’s room in your heart.”
just a little story: a neighbor of mine (VERY modern – not even sure if they fit into the MO category) was once talking about having kids and she said that her husband was worried to have more. my mother told her this. a year later she had a boy and when she called my mom to tell her about the bris, she said “i told my husband what you said and he gave in in a second.”
one more yid in the world!
