We helped her to understand that her returning to coddle her daughter actually made it worse. Even if they are insecure at first, showing them there is nothing to be insecure about is how they will move past it - not comforting them (which can confuse them into thinking there is in fact something to be insecure about).
The first two Sundays I had with her, she cried and cried. I didn't comfort her cries
Well we all parent differently, but I can't agree with this and if I knew my son's teacher did something like this (let him cry for a month and not even comfort him) I would be pretty sad.
I don't think we can say there is nothing to be scared of. Imagine you had been dropped off in a room full of strange people during one of those insecure times that the young ones go through and then when your mommy came to got you she wouldn't comfort you instead she said "there is nothing to be nervous about. pshaw!" or instead of a comforting teacher in this room full of strange people you found a teacher that just ignored the fact that you were crying rather than acknowledging it with a "its different to be left here, but your mommy will be back"
Jesus was kind to children, he liked them and treated them as persons. He said that we should be tender (like children) and treat others with respect, including children. I think we should follow his example,
Matthew 25:42-45 For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.' "They also will answer, 'Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?'
"He will reply, 'I tell you the truth, whatever you did not do for one of the least of these, you did not do for me.'
Mark 9:36 He took a little child and had him stand among them. Taking him in his arms, he said to them, "Whoever welcomes one of these little children in my name welcomes me; and whoever welcomes me does not welcome me but the one who sent me."
Matthrew 19:13 Then little children were brought to Jesus for him to place his hands on them and pray for them. But the disciples rebuked those who brought them. Jesus said, "Let the little children come to me, and do not hinder them, for the kingdom of heaven belongs to such as these."
If he is insecure or afraid, calm the storm by letting him know it's fun - talk about the class, teacher and the kids throughout the week at home so it's not so sudden and the routine isn't a trigger. Be gentle and reassuring but firm and confident so he mimicks YOUR attitude and will think positively about it rather than be confused with your frustration or concerns.
I do like and agree with this part though.

Positive talk is good, and when D wakes on Sunday I tell him its church day! Yay! That way he knows what to expect.
I would rather go for two times until my child felt comfortable with the proceedings enough to leave. When I left David and he was "ready" he still didn't want me to go, but he did fine, and then he told me he wanted to come back. When I left David (against my better judgement but there was a pushy teacher in that class) and he was not ready, for days afterward he told me he didn't ever want to go back and was majorly insecure and clingy for those days. I chose a church that was going to let me parent my children since I know them best.
Now if I could just figure out what to do with my infant
