My grandson's nursery can't carry on looking after my grandson now 2 years 9 months because he puts things like wood chips (in outdoor play area) in his mouth. Indoors he tends to eat board books. So he needs one to one supervision/diversion. My grandson is also non-verbal and the community paediatric service think everything is consistent with autism. Would be interested to hear from other parents whose children have/have had pica. How many children eventually stop eating non-food items? Or is it something that children are likely to continue doing from time to time?
