Yep, we all feel like that in the beginning! After I moved last summer I was down to one kid for a few weeks and then when I started filling up again, with each new addition it felt totally chaotic for a week or two. You will likely feel like that with each additional kid, but once they are all setlled, you will start to feel better and build up your stamina to it. My daughter was 8 months when I open my daycare (and my son almost 3), so I know how you feel! Get lots of sleep if you can...you will need the rest!
