Daddy Dom / Little Girl or Boy. DDLG, or DDLB, is a relationship in which one person is the caregiver or "daddy" and the other is childlike. It is NOT a relationship between an actual father and daughter or any minor. This is a type of BDSM relationship that may or may not involve sex, but often involves play with child-like things, such as stuffed animals, bed-time stories, and spankings. The LG/LB part of the relationship is often called the "little." - Urban Dictionnary
Example: (Picture on Tumblr of a pile of stuffed animals and a drawing of a rainbow surrounded by kittens and stars) Caption: I can't wait for Daddy to get home!
Ultimately ABDL is a very vague (and perhaps antiquated) term that is derived from the terms "Adult Baby" and "Diaper Lover". ABDL covers a diverse community of people who enjoy doing at "inappropriately childish things" like: wearing diapers, using pacifiers bottles, sleeping with stuffed animals etc... Despite the ABDL's community's origins as a fetish community, it has expanded to even include several intrinsically non-sexual subgroups. Additionally the community includes many people who take on nurturing or care taking roles for ABDL's. There are even some members of the ABDL* community who are simply incontinent people trying to find a way to make their incontinence "fun" instead of a burden. - AboutABDL.weebly.com
