When I had my last child I started my daycare when he was three weeks old and it was upstairs. I was nursing. So I made sure he slept in his crib with the door slightly ajar and a gate across so no one would go in. For the first month I nursed in the living room on the couch. After that I moved to the his bedroom in a rocking chair and left the door wide open. I made sure the children had something to do or put the t.v. on for 30 min. I made sure my son had a schedule from the get go. Nowadays I find more and more that the children aren't on a schedule at young age and that's up to the individual. I know that for all my children they slept like a dream from day one at home, ate at regular intervals after a month. So things were pretty consistent. My advice consistency. The children want it and the baby needs it, whichever way you decide to do it.
