Second baby

Sydney

I have my first appointment tomorrow with baby number 2 and my son will be a year on July 26th, this baby was even more of a suprise than him. I'm kinda freaking out. My step kids are close in age but I wasnt around them till the youngest was 3. I feel like I havent had enough time with baby #1. Is that normal? How does the transition go with such close ages? His youngest was 9 when we had my first. Any seasoned mammas have any tips or anything to calm the stressing.
