in the last 2 years i flew with kids at all of the above stages. this is my experience:
0-6 months: bottle + Pacifier=Sleep
6-12 months: bottle + Pacifier + lollipop= sleep and kept busy(more or less)
1-2 years: everything that is available mid flight+ people getting angry =nothing helped

2-3 years: Laptop+ Barney+ nosh+ occasional walks=managed the flights and would not have a problem doing it again
