When my children were young I struggled with very little money, one thing they rarely had was pyjamas, they usually slept in tee shirt and pants. I struggled to keep them clothed and pyjamas were an unaffordable luxury.
My mother in law would buy nightwear for her other grandchildren but not for mine, we'd had the temerity to move away and she always swore to starve us into returning. She blamed me for the move but actually it was her son who knew it was the only way to promotion. It didn't work, we never did move back but it made life even more difficult, we weren't hard up, my husband was just extremely tight fisted.
Anyway, I digress, because I couldn't afford pyjamas for the children we have reams of photo's of Christmas morning with the children opening their presents whilst dressed like tramps.
