I think it is fun to see the kids do the same activity and watch the differences in how they do it, both from a developmental standpoint and from a personality standpoint. We dyed eggs for Easter and this was the perfect setup to see the kids' differences. AJ started off, typical first born, telling everyone how to do it and giving a demonstration. As the big brother, he watched what his siblings were doing and was quick to tell them if they were deviating from how it had been done in the past. He also wants to be the first to do anything, whether it is being the first to get an egg or the first to innovate and try something new like dying an egg two colors.
As the second born, David wants to throw the rules out the window and marches to the beat of his own drummer. He also wants to do things quickly to catch up to AJ, so precision for the process (hold the egg in the metal scoop, David!) is disregarded as he works to do it more quickly and his own way, even if it means using his fingers and getting them dyed green. He doesn't care about the process or getting messy as long as he gets to where he wants to be in the end.
And then there is sissy. As the youngest and the only girl, she wants to be different and knows exactly what she wants. She will not compromise or take anyone's leftovers or advice. She wanted her eggs pink, pink and pink, thank you. She disregarded all instructions from her brothers that she had to use other colors, too. And in her rush to get some for herself with two brothers who are older and bossy, she just worries about herself and does not focus on fairness. There were 24 eggs, so we figured the kids would do 8 each, but Julia had dyed 12 pink before anyone realized that she was a little pink egg machine.
Much has been written about birth order and it's impact on personality. I will be curious to see if these characteristics stick for life.
