Can someone rest my mind? My mother said today my 19 month old shouldn't sleep with a cup of water in his cot as he could choke on it if drinking it without being watched in the night. Since I started putting his cup in with him he sleeps through as he likes a drink when he wakes up but doesn't need my assistance in doing so.
It's a bog standard nuby sippy cup.
Is this dangerous or is she being paranoid?
