Anxious about toddler with Baby#2 on the way

I have an 18M old daughter, and baby #2 is due 3 weeks after my daughter’s 2nd birthday. I’m already so anxious about how baby 2 is going to impact her life. I’ve heard an exact 2-year difference is hard because the toddler is at the height of needing attention and resents baby. My toddler is also such. a. handful. Her daycare teachers even comment on it. How do I handle two?!

For some reason I’m also incredibly anxious about how we’re going to potty train a 2 YO while simultaneously handling a newborn. Feeling like we should have waited longer between babes 🥺
