How every baby is different?

I wanna know some helpful tips, because i know every baby is different, but maybe some tips could help me out with - giving baby food to a baby who fusses about eating it and has only one thing she likes to eat - napping for only 45 mins - 1hr. ( i want her to nap twice a day for couple hours) - being able to clean the house, but have trouble cause baby needs to be picked up all the time. anything will help, thanks
