DD
Also called dd, DD1, DD2, dear daughter, darling daughter
DD stands for dear daughter or darling daughter, the way parents refer to their daughter online without using her name. A number after it, as in DD1 or DD2, tells sisters apart.
How it's said
DD1 is 6 weeks old and I had a quite traumatic birth so am prepared to be told I'm the unreasonable one here.
We bathed them together once dd2 was over the delicate newborn stage.
DD is nearly 7mo and is a bit of a nap refuser now.
Who says it
Where it came from
It's parenting forum shorthand, where the D stands for dear or darling. It sits in the same family as DS for son, DH for husband and DC for child. Dictionary.com lists it as used especially by women in digital messages.
The number after it first meant birth order, so DD1 is the eldest daughter. Some posters now use the number for age, which leaves readers asking which one a post means.
