What I'd like is advice not on how to disguise the vegetables, but to change their color completely. Something in a chocolate brown might go down easier. Thankfully, my daughter is not one much for temper tantrums. On the occasions where she has deemed it necessary to pitch a fit, she's been screaming too loudly to hear me speaking softly. Perhaps this is why Teddy Roosevelt said to carry a big stick when speaking softly.
Toddlers are incapable of understanding reason.
For months my daughter has been waking up in the middle of the night. She calls to me for one reason or another. So we had a talk. I reasoned with her. I told her that Mommy needs to sleep when it's dark outside or Mommy will be a very crabby person to live with.
