Because babies spit up.
There is no reason to change the way things are done, even if a mother writes an emotional article about it.
I’m happy to hear this mother takes her son to church, and that he’s hopefully learning to sit still and absorb what is going on.
But, she also sounds like one of these modern parents who can’t say no to her children, and becomes one of these parents who wants an exception to the rules and regulations because, well just because, her baby is sooo special.
