Dumb question: What are tags for on toys?

[Party-of-five]

once my mum cut a tag off one of DD1s toys and she was so sad she kept turning it round looking for it...mum promised to never do it again

From what I understand it is a sensory thing for them. Often the tags are silky material and not only do they like to chew on them they also like to rub them between their fingers, it is a comforting sensation for them.

Ahh, well that makes sense! Thanks

It's also supposed to help with hand-eye co-ordination
