My 18mo is breastfed during the day but has a bottle of cows milk at bedtime. Am doing a night flight to NZ and wondered what to do about this bottle. Should I take a bottle with milk in it from home (how to keep cool for a few hours) and ask them to heat up? Or should I ask when airbourne for them to fill a bottle with milk? They may not get to us for a while due to duties after take-off. Or take a carton of pre-mixed formula (he has had it in the past) and hope they can warm it up once in the air? Help!!
