Generally speaking babies under 2 years are not allocated a seat. In full service airlines - (Virgin, Garuda), you will probably pay a 'nominal fee' (5% to 10% of an adult ticket price) - and should request a seat near a basinet fitting (they are bulkhead seats - with slots into which the flight attendant will slot an airline supplied basinet).
Good Luck!
