question for moms who have had a second child

My first baby was a little surprise but we happily had him and he's become my world. Now my baby is almost 1 and my husband wants another. We have all the finances and everything in order to have a second child. In the long term I would love to have another baby close in age to my son, but I'm so scared about it in the short term! How did you know you were mentally ready for a second baby? How was your first pregnancy&birth; compared your second pregnancy&birth;? Was your first baby easy and your second difficult? Just give me all the info you can! Info about me: scared about pregnancy because I feel like id be signing up for 20 weeks of puking like my first. Birth had mommy complications that make me cry still. My first baby has been so easy so I'm worried my second will be difficult comparatively. I'm in my early 20s and I'm a little worried about my whole life being just about babies and tots
