No need to correct

When you observe your child engaged with a game/toy/activity, try to refrain yourself from interfering. You might see your child manipulating and/or using the activity in a 'different' way than it is intended, and that's ok, unless obviously he/she is doing something that could cause harm to him/herself, or to others, or to the object itself. If you interrupt his/her flow of concentration, firstly you become an obstacle in the process of development of his/her ability to stay focused; secondly you impinge on his/her developing self-esteem, having you sending a message he/she is not doing something "correctly". And finally you simply cannot teach him/her to "see" the mistake if he/she hasn't yet developed adequate cognitive skills.

You can approach the situation in two ways:

a) Ask to have a turn, and so indirectly you demonstrate how to use the equipment/activity;

b) Make a mental note and show the intended use of the activity on a different day.

Stop. Look. Listen. Think.
