hi, i'll also be flying cx's new business class back to canada this summer & my baby will be ~9 months then. i didn't buy a seat for her because i think she's too young to have her own seat. just wondering, for the take off & landing, will i just hold her on my lap? is there any type of special seat belts for infants? what about when they are sleeping? do they have to be strapped up? i'm thinking whether/not to buy the travel flight vest as well. thanks
