They all provide ‘oral regulation’!!
‘Oral regulation’ means any repetitive chewing/sucking which calms the central nervous system and also improves concentration. From babies with a dummy/thumb sucking, to kids and adults who suck lollipops, chew gum (think cricketers), chew fingernails and even cigarette smoking.
Besides the nutritional benefit, these ‘crunchy things’ provide wonderful oral regulation. I guess you could call them healthy oral regulation? And it certainly works with Master nearly4!
Do you or your child use any other items for oral regulation? 🙂 Heidi
