Both of my dd's have got into this, especially my eldest and now whichever one isn't first cries when they aren't. As there are endless things to be first at, this is getting ridiculous, and extremely annoying. I have to say, I think it is led mainly by my eldest - who is quite obsessed with being first in everything. We have never really emphasised it to my knowledge, and have had talks about how "one can't always be first, and what is so bad about second anyway" but to no avail.
How do you/ would you deal with this scenario?
