Hey Danni,
We travelled Syd to Cairns when Natty was 4 months. I didn't realise that babies have to wear a seatbelt that attaches to your seatbelt... at all times when the sign is on. I thought I wouldn't be able to feed her because of this... I thought she had to be facing forward and I knew that her ears were bothering her on descent.
However, I've since chatted to other people who said that you can put their seatbelt on loosely and turn them around and feed - it just didn't occur to me Anyway, just thought I'd let you know in case you were surprised like I was by the infant seatbelt.
Have a great trip!
