Trying so hard not judge .

I work in a daycare at a gym and there is one mother that goes there makes me feel uneasy by the way she parenting her 4 kids . 1. She hits her heads on the head. 2. She swears at them. 3. When they actually being nice, in a joke matter "I think" will say something rude back. For example they'll be like mom !! You're back !!! And she'll say something like oh great and make a dirty face. 4. She lets her kids do whatever they want like climb thigh they're not aloud too. 5 I saw them wear the same pj two days in a row. 6. Sends naked pictures to guys 7. Goes out every weekend. 8. One time her oldest which is 8 asked me to sit on his lap. 9. I can go on.... 
I am no one to judge but this has been going on for awhike. Maybe it's just me .
