Pregnant with a 9 month old

So after having my daughter we knew we wanted to have more kids and my husband and I want to have kids sooner than later. I didn’t start taking birth control or anything so we werent not trying but I wasn’t tracking the days I ovulate etc. I was all in ready to have another baby and all the sudden that I’m pregnant with a 9 month old reality has set in that I’m going to be pregnant again for 9 months haha. Don’t get me wrong we are sooo happy but lets be honnest I’m so exsausted and sleep deprived it’s not even funny. But my daughter is so worth all of it. Any other moms in the same situation? Or have tips/advice? Was your secound pregnancy the same or different? How was labour? Same different? Man I’m dreading being extra tired and sick feeling with a 9 month old.
