In sims 2 How do you change your baby sims diaper?

Hey:) it is very easy to change ur sims baby diaper... you either click on whoever you want to change the diaper: ie. an adult or maybe teenager. once u r selected on them u click on ur baby and then "change diaper". or u can buy a baby change table and use that. u get a baby change table from the same area that u get ur baby cot. xoxo ps. good luck
