These will stay put, but only in my cupboard!
The main reason I purchased these (apart from the pretty colours) is that my 14 month old son thinks it is funny to throw his bowl if he does not like the look of his lunch. These do not stick to any surface, not even for a few minutes. Also they are not microwavable and cannot be used with washing up liquid that is antibacterial - but you only find this out once the item arrives and you read the packaging.
Please do not waste your money, you will be disappointed.
