Well, speaking only from my own personal experience: first two children, same dad (husband #1). I worked only part time, did at home day care with 2 to 4 other same age children when I wasn't at work outside the home. They are both gifted (I'd say Ruf level 1 to 2).

Last two children, same dad (husband #2). I've worked full time, they've both been in daycare full time from 12 weeks old. Not someone's home daycare but a daycare facility. DS7 is highly gifted (Ruf 3 to 4) and DD3 shows signs of being a 2 to 3. I honestly don't think that being in daycare could prevent a child from being gifted or showing signs of it, unless it was a situation of significant deprivation for the child in terms of stimulation and opportunity. I think I lean more toward nature. Nurture is how well it shows itself and when.

My current husband says that I upgraded my breeding stock! He apparently believes it is ALL nature!!!!
