Expecting baby #2 & scared.

Hello ladies & possibly gentlemen. I just have to get some stuff off my chest. I am currently 6 weeks 3 days with my second child. My first son is 18 months & that little boy is my world . I love him so much he’s my baby. The new baby will be due in July, shortly after my son turns two. I’m really scared that once this baby comes I’m not going to be able to give my son all the attention he’s used to. I’m scared that he isn’t going to feel as loved. How was it adding a second addition to your family when the first is still so young. I’m scared because he’s so used to getting all the love and attention. I don’t want my son to feel like he’s being loved any less. It worries me
