It is hard when the little ones leave for a bit - but it's very healthy for them and for you as well. Trust in the teachers - get to know them and talk with them about your kids. ONce y ou are comfortable with them, not only will you feel better, but your kids will pick up on your comfort level as well. GOod luck and by the way - it's a graet place for little ones to go and begin their exposure to religion. Easy going and non-threatening!
