Recently met up with friends and their preschool DC for a day out.
Friend A's son is potty training currently. (Friend B's son, and my own Dd have been trained over a year - this is relevant!)
Friend A's son had 3 accidents needing a change of clothes before lunch. Then after lunch, B's son wet himself, and B didn't have any spare clothes. B asked A if she had any spares, and she said she only had one set left, so wanted to keep them in case her Ds had another accident (bearing in mind he'd had 3 already). B was v taken aback and a bit pissed off.
Then I managed to find an old pair of spare knickers and blue flowery leggings of Dd's that I must have been carrying around crumpled at the bottom of my bag for the past year and offered those.
B refused them because they were for girls and she wouldn't ever do that to her DS. She said A should take them "just in case" and lend her (B) her boy's clothes. A wasn't keen, and said she'd rather just keep her own clothes.
B went home early as her son had no clothes to wear, and later posted a PA Facebook status about knowing who your real friends are.
I reckon A was justified in hanging on to her Ds's clothes.
But I don't think a 3 year old will be that scarred by wearing some flowery leggings for an afternoon, so I think one of them should have taken them, rather than B having to go home, so I think if I had been A I would have just taken them to keep the peace!
