OK, I admit I'm not the most maternal person, but I like kids in small doses. Heck I even like seeing the odd photo now and again. Oversharers can get a bit annoying but heck - I'll indulge it.
But what on earth makes you think I want to see pictures of your child with its face covered in food? Mouth agape with half chewed mush, a kaleidoscope of liquefied food and saliva dribbling down its chin. It's not cute. It's not endearing. It's about as appealing as sending me a picture of its unwiped behind.
Maybe I'm just a bit too OCD but I honestly I really don't get why this is 'a thing'.
ps. I also have no wish to know the blow-by-blow account of your child's potty training either. TMI.
