My mum has slagged off every name I have chosen for my kids and is doing the same with this pregnancy.
I just remind her that she has named HER babie's, and now I will be naming MINE, regardless of what she thinks. I also make a point of telling her how much I hate every single name she suggests, which in most cases I do anyway, but quite often say so just to spite her, cause I am childish and hormonal and it makes me feel better lol
