This passed my mind also. I refused to buy expensive clothing for my young children, especially pjs that would be grown out of rather quickly. With the addition of a tight budget, I don't think its an inappropriate suggestion that the clothing could have been of a quality that was easily damaged.This isn't snobbery before anyone accuses me, it's because I've lived a similarly low income lifestyle for many years... they may have been relying on the cheapest possible clothing. I don't know what shops there are in that area (I've been out of the UK a long time) but when mine were little it was Matalan, George at ASDA, that sort of thing. They're worn out after a few washes.
