I want to use my old password

fiew days ago my 4 years old son was trying to type something on iPad - in password field.

So apple reset my password, I had to use new one, and then I coldnt't change it to old one....

Now i typed wrong letter when typing my password... Same story ... after reseting, I cannot set my old password that I finaly remebered.

Is there any way to use my old password again?

I'ts not helping whith safty when every time I make I mistake I have to make new password. It's crazy.

It's ok if apple tell me: Hey, U've been using this password, are U sure U want to use it agan? - but no, they just don't let me.

It's so stupid...
