DS has wet through his nappy (not last night) but the night before.
I washed the sheets and mattress protector and checked the mattress and it seemed dry.
Obviously not as today I could smell that horrid stale urine smell.
I have washed the area with clothes detergent, sprayed with vinegar and bicarb and water mix. Blotted and repeated.
I have sprinkled with bicarb and dragged it outside in the sun to dry.
What else can I do?
It's a brand new mattress and cost a small fortune, and I want rid of the smell completely.
