I certainly agree with this. I know we tend to compare our selves with others, especially when we became a mom. And of course that comparison of children will follow too.
I must admit that when I was a new mom, I can't stop myself from comparing me being a mom and my son with other moms and children. But as I go on with motherhood, I learned that I am a unique mom and that I have a unique son too. I learned to accept that I can't be a stay at home mom just yet. I learned to accept situations that happened beyond my control. I trust and believe in God. For He always has a better plan.
There's no perfect way to be a good mother. I certainly believe there's no good or bad mother. Because at the end of the day, the love of the mother that really matters. For a mother will always love their children deeply. That is unquestionable.
