my mum likes to suck her finger, she sucks on the straw when her drink is finished, she puts almost everything possible into her mouth. Has anyone else had experience of this? Is there anything out there that I can buy that she can safely put into her mouth? When we were holding hands last night she was trying to put my hand in her mouth! We were rummaging through ribbon on Monday and that too went into her mouth. Any suggestions, guidance, advice gratefully received.
