Also keep in mind that the kids will all age month by month which can make some things go a lot easier. At minimum they know the routines so will just automatically go take their shoes off when you say time to get ready for nap. The baby that needs fed bottles now will only be doing that a couple more months then taking a cup like the rest of them. The one not walking will be running before you know it.

What you might want to do is just wait a couple months and then add the next child then once the group you have now is ready so to speak.
