God does not allow us to cry alone when we are crying for Him. No, He doesn't give us what we want, but He doesn't put us in our bed and leave the room for us to cry ourselves to sleep without Him.
You'll feel like a horrible parent, get used to it. If you were the best parent in the world, you'll still feel awful whenever the child suffers or stumbles. I came to conclude that that feeling was a sign of good parenting.
My oldest boy went into these massive screaming fits about a half dozen times before about 2 years of age. I would go over him with a magnifying glass trying to find a bug bite, a pin prick anything to explain his crazed screaming. We could never figure it out. Picking him up helped some, but not always. I worried that he had appendicitis or something bizarre and painful internally- nothing. The Doctor just smiled at us like we were first time parents (which we were) and that was that. Finally he stopped.
No answers no explanations. When I ask him about it now (he's a high school senior) he just shrugs. He tries to play it off like it's all part of a master plan he's been hatching since birth. When he was a toddler the little tyke used to take food from the kitchen and hide it in his room; sort of like he suspected that one day we would stop feeding him. My wife would find crackers and cookies neatly stacked up out of sight in hidden places.
