I have 3 affected, one not. It is HAAAARD. Not so bad with them spaced out to 3 years, but still a lot of work. I love them to death, but I'd go completely bonkers if I had them closer than 3 years apart.

My 6yo is in K. He gets up at 5:45am to get his bath routine done in time for school starting at 8. We barely make it out the door, and that's with me making his breakfast and lunch and doing his creams and clothes while my husband takes care of the shower.

My 3yo is going through the stage where he fights most of his personal care. My older one did this, too. Showering is an emotionally draining experience when you have an hour of your child screaming "I DON'T WANT YOU!!" when you try to rub the skin off or file or get the scale out of his hair or cut his nails or anything. Then once out, he doesn't want cream because his skin feels good and you can't explain to him that it will dry out in an hour because he has no sense of time. Plus he's still a little clumsy when walking, so we have frequent bang-up injuries from falls.

Then there's the baby. He's 7mo. He's a lot of fun, but still needs a lot of attention, as all babies do. Some days it is challenging to find time to bathe him without the other 3 getting into a fight or making a mess. I usually pull them all into the shower with me so I can babysit, but then when we get out, I have to get 3 of them creamed before they dry out. now that it is summer, I am often feeding or changing the baby and the older ones are demanding a drink and someone always ends up waiting.

In the middle of that is my girl. She's not affected, but needs a lot of attention. I think she frequently feels left out of the bath routine. I can get her shower done in 5 minutes. She doesn't need cream. She always wants a drink when I'm providing for the boys. Next year she'll be in K at the same school as my oldest. Her ability to get to school on time will be dictated by my son's schedule. Yesterday, she missed out on a petting zoo field trip because it was too hot for her brothers to attend.

So, frankly, I think you'd be an idiot to try for a baby without waiting a couple years in between, seeing how you have even more issues with your firstborn than I do.
