Low lying placenta (previa)

Hello! Just had my ultrasound and found I was having a beautiful baby girl which I’m so excited about since I have a 16 month son at home. I also found out I have low lying plecenta and that I should not lift over 10 pounds and rest as much as I can. I’m freaking out because I don’t see how it’s possible not to lift toddler. Did anyone have this in second trimester and it turned out okay?
