Pica

She could be a Chef or a Botanist in the making!! This coudl be a tactile approach to understanding the world around her and is fantastic especially if you can help her engage and explore properly. 

Start a garden? Get her even more connected to the Earth. Maybe find childrens books on foraging. Join online foraging groups and get to know how incredibly brilliant and creative these humans are. If she's doing something naturally, help her understand how to engage properly (which may take a little research!)

ON the other hand: My son like chewing pencils and plastic, so I taught him how to chew gum at age 3. And then bought him chewing gum in PACKS. If I noticed him chewing mindlessly on plastic (it was a need to chew rather than a tactile sensory engagement), I'd hand him a stick of gum. On a side note, if worried, his teeth are in excellent condition - he's 25 and never a filling. 

There are things to be heartbroken over: a lack of ability to sense cars on the road, an inability to sense the danager of fire. My father and brothers all chew on ice non-stop. My father will always have an icemaker in his fridge. His mum would always leave carrots, radishes, peppers and other cold fresh veg pre-cut availalbe ALL DAY for this very reason. He chews on ice while coding programmes for robotics. 

Thank you and hope she will understand the danger soon. 

Thanks. She is very picky with food, will try. 

Thanks. Agree will guide her for sure and teaching her finding safer alternatives.

Thanks. Referred to a blood test since the last time was a year ago. I started giving her iron and zinc supplements.

i had pica as a child, i would eat lead pencils, wood, hair, paper, sand, plaster, glass. as i got older i understood the danger of doing it and that made me stop, thats the only thing that did, also 2 of my kids had pica, with them i found sensory chewers on a lanyard worked ok, it was hard finding the right texture for them but when i did it worked, i explained the possible dangerous side effects too and by 10 they both stopped pica.

my son used to eat alsorts ,elastic bands, paper ,tissue ,wood ,snails . he did grow out of it at around 8 ,i would try to guide, her edible flowers and leaves . it is better to now what they are eating ,than putting to much pressure so they start hiding it. 

If she isn't Vegan, I'd suggest Liver as a source of Iron.

Hi, I assume you've spoken to your GP as well and had other bloods done? Don't know about people but in animals pica can indicate anaemia. Otherwise, I think growing and planting edible things with your daughter, as others have suggested, and gathering them with her and making proper food from them, might be a good way to redirect her? 

Both my children are the same but with different objects

Could you give her mint leaves, herbs. Search up edible flowers and maybe plant some of these things in your garden/balcony/windowsill. Allow her to do it safely. 

Thanks for your comments. 

Yes. We saw a nutritionist on this and did a blood test on her, the iron level is fine. I don’t know what else I can do. 

i heard one time that having the urge to eat dirt or something abnormal is a sign of some sort of mineral deficiency and your body craving some sort of mineral... probably iron maybe?
