Hello Lal Sir !
I tried reading the link you shared about the deep kindness of parents. It lead me to this page-https://www.buddhanet.net/e-learning/filial-sutra.htm
I feel that this can’t be Buddha’s words as it has a major flaw. The number of bones in a fully developed foetus is told as 360 which is actually 270. So I feel that some ignorant person has added this sutra to the tipitaka later.
