DD (just turned 2) had an episode with washing machine at 90 degrees and a pack of crayons. They melted into nappies, and despite my best efforts had to chuck them away
She has 2 left.
Most brands don't go up to 25 lbs, so need suggestions until she is potty trained (which she is showing zero interest in at the moment!)
Not a total loss as DS will wear them later.
