Travelling from Birmingham on Friday with 13m DD, first time we've had to contend with this this as last time she was still ebf. I've found some stuff on govt. site saying you can take formula and sterilised water in bottles, but DD only drinks from me (morning and evening) or from Tommee Tippee sippy cups. Is there a problem taking empty cups, as these are over 100ml capacity? And will they allow them if they're filled with cow's milk or juice/water?
TIA
