All depends on the kids and their background, imo. I second the day care working being put on hold though if you adopt a sibling group. I spent ALL of my time with my kids that first year and it was necessary. There is no way I could have worked that first year, imo.
For me it wasn't so much the number of kids being around and the adjustment to no kids to 4, because I think going from zero to 1 kid is quite the adjustment too. It was the developing of relationships with each one and fostering their sibling relationships too all at the same time. That was VERY time consuming and overwhelming at times.
