i will second binyamin
this is a very sensitive issue we should teach our children according to islam but at the age when they should know wat they studying not at very this stage they should be bit mature u can start teaching such stuff after primary but not in 2 class a child is to young to understand the importance of such education.
before primary we should make our childrn study not only basic islam but important social issue discussed by holy prophet and the importance of paradah n haya not only to girlz but to boys also. 1st hv to make foundation for the study n than start not like this.
we should realize the fact children are curios so avoid such things at this stage
may b am wrong but this is my personal opinion
