worried about 2nd baby

When I first found out I was pregnant again I was happy! My husband has wanted another baby, our daughter is only one year old. I’ve seen my baby twice on ultrasound and heard the heartbeat today, it made me so happy I cried! I get into those days where I think about is this new baby so much and I’m happy and I’m excited and I also have those days where I don’t think about my pregnancy at all. I guess I’m worried I’m not as connected to this baby and I’m not going to love them the same as my daughter. I feel stupid saying it out loud but I’m really scared that I won’t have a connection to the baby. I was obsessed with my daughter during pregnancy that’s all I thought about and planned for everything during pregnancy. Is this normal? I’m so nauseous so it’s not that “I’m not having symptoms so I don’t think about it” I’m nauseated every single day, and I throw up randomly. I’m only 10 weeks. Please if you’ve gone through something similar share your experience. Does it get better?
