I have 6! 4 girls, 2 boys, all fixed. As for schedules, they are all on the same. We all get up around 7, they all free feed, so there is no food schedule, last call on pottying is at 10 and we all go to bed at the same time.
Any new baby is always a bit more work, but once they get a bit older, they too will get on schedule. Everyone always asks me how I manage 6, but it just happened! I can't imagine managing 6 kids, but dogs, that I can handle!
