I'm not bothered by acronyms I know they are widely used on this site, I don't bother with the prefaced, initial "d" whether it means dear or darling I've no idea, but I don't use it, each to their own. I was perplexed over on MN reading through one thread where the OP kept referring to her "LO" couldn't for the life of me work out what or indeed who that was until I tumbled "Little One" seemed a bit twee to me, why not baby, toddler, child, son or daughter, but hey ho we're all different. I think it's up to the individual how they wish to post or refer to members of their family.
