Birth control after birth?

i am going to b 6month next week but wanting to get a head start on birth control after birth so i have all the info i need. i was thinking of getting my tubes tied but u never know i might want more in the future (this is my 2nd) also i don't think theyll will do it cuz i am still young. no pills or shots i know that i will not keep up with them. what are some other methods i can look into.
