Ok, long story, I went to a party yesterday for my friend's baby who is the same age as my DD (a few hours younger), they are both 1.
My friend's DD is tall for her age, and weighs 25lb, she is walking, my DD is just under 20lb, crawling like crazy but not walking, and looks 'small', she is very healthy and has no problems.
My friend introduced me to a relative (can't remember exactly the relationship) who looked at DD and said 'Aw, bless how old is she?', I answered that she was the same age as (party baby), and this woman responded 'oh! She's very small isn't she. She's a bit runty, is she healthy?'
I made a polite but swift exit from the conversation (before I was too tempted to force-feed this old fart bag lady several large sausage rolls.
I heard her use the term several times during the party, refering to my DD as 'the runty one'.
Was IBU to want to scream 'just cos (friends DD) is bigger than mine does not make my DD runty!!!'
