Pregnancy/postpartum

Hi everyone. I just found out I am pregnant with my 2nd baby. I'm 6 weeks pregnant.  My first child is 14 months old. She is amazing. A very easy baby, easy pregnancy. However, I did experience postpartum anxiety after I had her so i am kind of nervous about going through that again. I was wondering if anyone ever experienced it with their first and not again with their 2nd?
