We don’t live in a sterile world. Her hands are not sterile, the toys she plays with are not sterile…. I understand you’re trying to be safe but there’s no point trying to keep one item sterile in a dirty world. She will chew on her blanket, her sleeves… anything that’s available. Be clean, wash everything as you would normally do. Babies have to be introduced to germs to build up immunity
You could use Milton spray on them?xx
