What is the best age to introduce your kids to pet? I want to teach him reponsibillity by having one.

The answer depends on the child and depends on the pet.I have seen a lot of advice suggesting that a good time to introduce a pet is when the child is 8-10 years when they are responsible to do their own daily chores independently. Pets and young children should always be supervised. Never allow them alone together until the children are old enough to fully understand how to interact safely with animals. We had a pet because my son desperately wanted one and dad thought of teaching responsibility through having one pet- fish. But after a while he lost interest and ended up in daddy washing and cleaning the fish tank without any help and my helper feeding the fish. Be patient enough to settle all the arguments with the siblings on whose turn is to feed and whose turn is to clean. Be careful not to have any argument over pet related chores and don’t threaten to get rid of the pet even if she or he doesn’t do their share.
