I started my home daycare when my dd was 6 mths old and it really helped to have other children that were close in age. At that time I had dd, a 4 mth old, and an 8 mth old. They all napped twice a day at the same time and activities were easy because they were so close in age. I think the most important thing you can do is get them all on the same nap and eating schedule as quickly as possible.
