I opened my daycare when my youngest was 3.5 months old and my oldest was 2 years old. Before that I was working in a daycare since my oldest was 7 months old, so I was not to worried about his reaction of me starting a daycare as he grew up in the daycare setting. Now, I am expecting number three at the end of April and plan on taking off 2 weeks, then I am right back at it.
