My real concern on both a selfish and a sympathetic issue is the mother of the toddler or baby who cannot have a sippy bottle on flight any longer. They are going to be at the mercy of the flight attendant bring them something to fill a bottle or sippy cup with. Children's patience levels are not compliant with sanity for such things.

I think in 5 years we shall have to wear approved flight 'Johnny's and check our clothes as well undeneath.
