Hi, It's never nice to have to do the flight back for something like this so i feel for you. We had to do it reverse when we lived in Oz and it is the phone call you dread. Mini patt was born in Sydney and we moved back to London when she was 5 months old last August so did the reverse trip. She is a 'Neocate baby' and it was pretty similar getting it there as here, if you don't have a prescription it is about $60 a tin though. Most pharmacies need to order it in but this only takes 1 night. I posted 8 tins and took 8 in one suitcase and customs were fine with both. It would be worth taking your Dr's notes and copy of prescription with you in case you run out as you might be able to get the Dr to issue a script there but i found i could only get mine from my peadatrician and as you pay around $300 to see one of those it may be cheaper to buy Neocate depending how long you are there. I didn't find the flight as bad as i thought and my daughter has always been a rubbish sleeper (off topic but am sure there's a connection with dairy intolerance, neocate and bad sleeping?!), she slept for about 6 hours of the first leg and 4/5 of the second. In between she liked playing with the remote controls, having a go on the headphones and walking around looking at the lights. I flew Thai and they were incredibly good with me having a child and very helpful. Jetlag for the baby wasn't too bad either and i think having a bad sleeper actually helps with this as it's not like they have a perfect 7pm-7am routine that gets disrupted! Anyway good luck and if you have any other questions re neocate etc feel free to PM me.
