HI
I would suggest for the airports to have a stroller that folds down like an umbrella. These strollers can be taken to the gate which makes life easier. As she is 9 months she will be eating meals on the go, so again the stroller is a good place to feed her.
Travelling
When travelling with your baby the first day of travel is always the hardest as you are having to take into account the time changes. I tend to mix and match on this day – sometimes they get an extra feed one way and the other way they may lose a feed – it all balances out in the end. I try and put them to bed as close to the new time change as possible and when they wake up in the morning I go straight into the new time zone. When doing this it is important to remember what the old time zone was so for the first couple of days they may need to be encouraged to eat well during the day.
I have attached notes on how to pack and travel
