[blindkid] Walking in a line/cane use

[L]

Hi All,
A couple questions!
#1.  My daughter is almost 4 years old and is in an all day long Headstart 
preschool program.  They have to walk in a line to and from classes, cafeteria, 
playground, etc.  How exactly do you help your child/student walk in a line.  Is 
it appropriate at this age to hold the hand/arm of an aide or teacher or 
appropriate to hold the shoulder of a 4 year old student in front of you.  These 
are the two things they are doing now.  Is this how your children learned or is 
there a better way?  

#2.  Also, in a small classroom, do your students use their canes throughout the 
room, or do they hang it at the entrance of the class when they come in.
Thanks for any input you can give me!
