One of my grandsons is the same way. I try not to work on the tank when he is around. If I am mixing water, he has stir it, and then help me pour it in the tank. If I am draining the tank, he is there too holding the hose sometimes in a buck, other times over the carpeting... the fingers are always at the end of the hose splashing everything in reach. When he was about 2 he loved to look in the top of the tank and run his fingers through the water. He is 3 years old now.
Kids are so cute when they are young and willing to help, then something happens. I think it is called growing up.
Rangermonroe, you have a cute on there, best wishes
