Things that make my boy cry, a lot:
1) Changing his bedsheets.
2) Changing his bedsheets to Winnie the Pooh bedsheets (previous ones were plain green).
3) Having a runny nose (inevitable once he is on a good teary tantrum about the sheets).
4) Getting snot on his hands.
*As you can see, bed time last night was an ever-escalating series of traumas.
