Ds1 and dd both chose their 1st outfit to buy at about 9mths old *sigh* and that was a bad sign. Ds1 has always been picky about his clothes but at 6 he can dress himself. Dd at 17mths can't articulate why she wants something but can be persuaded to change sometimes. Ds2 has his likes but doesn't really care what he wears. I put away clothes that are too big/small or out of season.
