1st Born feeling left out

I have a almost 2 year old baby girl. I just gave birth to my baby boy. I will be discharged tomorrow and will be able to go home. I miss my daughter so freaking much and I’m so emotional on how she will feel. I feel like I let her down in a way because she won’t have my full undivided attention once I get home. I’m literally in tears because of it. I will do everything in my power to give her attention at all costs. Is this normal to feel this way or has anyone else felt experienced this?
