Mothers problems 😩😩

I'm getting tired of my mom always asking me for money she know I'm about to have a baby in 7 weeks or less she acts like I'm rich or something the baby still doesn't have much clothes, he still doesn't have a car seat, stroller, blankets, swing , bouncer etc. we not rich we have 4 kids and 1 on the way especially school around the corner I've to buy everything for them for school my mom just don't understand anything about life. I told her I don't have she gets mad and says I will never help some one again she just don't understand I try explaining it to her it seem like she don't care, and she just don't call me asked how's her daughter doing never she gets mad about money all the time
