Have you ever taken advice about parenting from someone who has only one child? Now was it good advice? There is good advice that can come from people who have only done things once. Ask another parent not from the same clique though and you are bound to find a different perspective.
We are made to feel that often the only time we are entitled to speak is if we have years of experience and have done things a hundred times. That is not true. Do not be afraid to share your opinion on things. At the end of the day, the most important thing to remember is you do not control someone’s choices even if they ask for advice, you are only giving a one sided opinion.
