I'm so tired of living with my parents and hearing them arguing about us. We stopped buying formula for my daughter after she turned one bcuz she eats anything and everything but my mom still thinks she needs formula so she's been buying her toddler formula which is her choice I'm not asking her to. Then my dad gets mad saying that they are providing everything for my kids. Like hello I don't think so. I'm so grateful for them letting us stay here but he thinks that means he gets to dictate our lives and its really putting a strain on my family.
