Europe for 6ish weeks. Visiting 3-4 countries staying few days in ea location
A) Would you prefer to go with 18 month old and 3.5 year old or
B) 2.5 year old, 4.5 year old and 4-6 month old.
Older child is already toilet trained. Younger child hopefully will be by 2.5 years ( doubtful at 18months)
Option a is cheaper flight wise but unless we are lucky to get a spare seat next to us we'll have an 18 month old on our laps for 24 hours ( unlikely to get bassinet seat due to age).
Option b is more expensive but we are highly likely to get bassinet seat due to youngest age and two others will have own seat.
