We have three children: ds1, dd, ds2.
DP would say "ds1, ds2 and dd".
dd and ds2 are twins, dd the elder by 6 minutes. I order the children strictly by age, dp claims to do the same, but obviously doesn't, as she always puts the boys first. She says I'm silly to even notice.
I don't want dd to always come third in the list because I don't want her to get the message boys always come first. Am I over thinking this?
