Looking for a bit of advice. My toddler (just turned two) has recently started picking at her nails. She only does this when she's calm and relaxed - watching TV, while reading a story at bedtime, and after I've put her to bed (where she'll lie for 15/20 mins just picking at her nails before she goes to sleep). She's not doing any major damage at this point but they are very short and ragged looking. I'm also fairly sure it's not stress or anxiety, but how do I get her to stop? I've tried brushing her hand away but she just gets agitated, and I've given her various soft toys/muslins to fiddle with instead but this doesn't work either.
Does anyone have any experience? I didn't know this was A Thing, so I'm at a bit of a loss for how to handle, or whether she'll just grow out of it!
