Luckily we can always we can always go with "kid's are resilient. As long as the parents are flexible and willing to drop any plans and change direction within 15 minutes of hearing a convincing reason..." the family will be fine.
Right now I'm putting a variety of activity's on the boy's plate with the minimum expectation that he be willing to dabble in everything and letting him determine the depth. From what I'm reading online this could be wrong. If I let him chose only his preferred activities he will learn to operate at a deeper level which is transferable to every other activity. But I think he'll have access to his own natural depth either way. I tell myself, "every mother must over-think every little thing too much.". " Just quit thinking and go vaccum or dust the furniture.". I tell myself, Lol.
