Question

Is it bad if I leave my 2 daughters in our apartment while I take my son to his bus stop?..

The bus stop is literally outside of our apartment like literally we live upstairs but the bus stop is right in front cause we live in front of the street . Well anyway sometimes at that time my daughters are already awake cause they wake up early but I find it better to just leave them here watching cartoons while I take my son outside I find It not necessary to put sweaters on them and shoes when it's right out our door . And it'll be quick as well as after school I find it easy to just leave them for like 5 or 10 minutes. Their ages are 3 and 4 . And of course I make sure all our windows are closed and locked including our balcony door I make sure everything is locked. What do you guys think ? Like I can see the bus coming from our window so I usually just run out when I see it
