Need honest opinion

Ok here is the short version of my situation. I have 3 children ages 8, 4 and 8 months. My husband and i agreed we would have a 4th baby but the 3rd and 4th would be close in age and at a year we would start to try to conceive for our 4th. Having 3 have to my surprise been great, i defiently want a 4th but because all my other kids are exactly 4 years apart having another so close to another scares me. Can anyone please share your experiance with have kids close in age...i want some piece of mind that even though my third will almost be 2 by time i deliver i wont be drowning in my own life lol 🤣

Thanks for reading!
