This topic is interesting to me cuz i used to tell my husband that i was afraid of having too many children that we couldnt afford. Myhusband always said, Hashem knows what he is doing and to whom He is giving what, and what He gives is what we can afford or we will make ourselves afford.
And you know what? He was right! time and again Hashem proves to me that He is watching out for us and there for us!
Whether its in the form of a bonus from my boss or his, a refund from somewhere, a gift from a relative…it just comes!
