I’ve always worked so deciding to be a sahm after our third baby has been a major adjustment and I feel L A Z Y! Is this normal?

My day consists of dropping the two older kids off at school, coming home, do whatever housework needs to be done or shopping. the rest of the day I’m taking care of my 6 month old and relaxing (watching tv or napping when baby does)... I pick up the kids from school, make dinner, entertain them until I put them to bed around 7:30/8.

Am i doing this stay at home thing wrong???
