Still eating toys

Hi! Is anyone else’s almost 2 year old still eating toys / putting everything in their mouth?? My daughter is constantly eating/ biting / putting things like stickers, books, soft toys, figurines, cars, magnets (not little ones, ones that go on a magnet board) etc.. She’s told off every time for it and gets so angry / upset. She has all her teeth for her age and has for months so it’s not teething. She doesn’t have a dummy or bottles and hasn’t since 16 months old. It’s not any specific item she goes for everytime, it’s everything she can get her hands on, for things like books/ paper, stickers and magnets (again not small magnets, I’m talking about the full black back ones), she eats parts of the things. Her fingers are constantly in her mouth and anytime she’s told to stop or to take the things from her mouth, she screams, cries, tantrums and gets so angry ?? Her development is on track so this just seems so abnormal, she knows she’s not allowed to do it too cos sometimes she checks if I’m looking at her and smiles a little if i am looking at her as she puts it up to her mouth??? I don’t understand ?? Is this pica??
