As Simple as it looks to me, I don't understand why my child's legs are not straight / toes are
not pointed.......

Good comment...... but the truth is..... look at how we walk:
Heel first / bent leg ...........
Now, ..... how many steps do we take in a day????
Multiply that by 365 days in the year --- and multiply again by your child's age.... and this is
how many times he / she has trained his / her foot to step heel first.....

and now, in a 30 / 45 / 90 min class once a week - this is supposed to be altered???

Practice, practice, practice..... don't let your child just sit and watch tv.... even if it's just at
commercials - be sure they have practice time -

While they are watching a siblings soccer game...
While they are riding in the car.....
Instead of fighting with their sibling  :)
