Help with toddler parenting

Hi mamas,

I was wondering if anyone had advice on parenting a toddler. My son is 2 1/2 and I’m a sahm and pregnant with my second baby. In the last 3 ish month I would say, my toddler has taken a huge turn and suddenly won’t listen to me at all, ignores anything I say (like what do you want for breakfast or how are you etc.) loves his dad, tells me he doesn’t like me. The list goes on. I’ve really struggled with parenting since I got pregnant because I was so sick and tired during the first trimester but I’ve just turned into this mom that I feel isn’t nice. I raise my voice and gets so frustrated so fast. Sometimes I’m afraid I scare him and I would never intentionally upset him but every single day is a battle for us and I’m getting so sick of it and I feel like I hit my breaking point in two seconds. Which is when I end up raising my voice. I have a suspicion that he’s watching too much tv (I would say at least 2 hours a day) and I’ve been working on keeping my phone away while he’s awake but I’m just getting so sick of the constant battle. The never ending not listening is so exhausting it’s like we can’t do anything. Does anyone have any tips on what helped if you experienced this? I think I jinxed myself because he’s always been an angel child and now I feel like we’re losing our connection and just battling eachother all the time. Help. 😭
