Bit of a strange post. My 18 month old has started a habit of chewing food but not swallowing it. She'll have a bit of something, chew it thoroughly then keep it in her mouth rather than swallowing it. It eventually makes her gag and sometimes sick, she won't swallow it or wash it down with a drink. She gets upset by it being in her mouth and afterwards won't eat anymore. Anyone experienced similar and have any tips or ideas of what has caused this?
