Here is where we have been with Kai since he was born
June 2006 - Kai was around 5 months and went to England for just over 3 weeks. 2 8 hour flights both ways
August 2006 - Kai was just over 7 months and we went to New York for 4 days. Just an hour flight from here
November/December 2006 - Kai was around 10 and a half months and we went to Madrid for 1 week and then to England for another week. 2 10 hour flights (plane had to stop for 2 hours both ways) and then the flight to Madrid from Gatwick which was 2 hours both ways.
February/March 2007 - Went to England for just over 3 weeks. Kai just over 13 months
April/May 2007 - Going to Chile/Argentina to see Kai's family on his daddy's side for about 2 and a half weeks. We leave here on Thursday at around midnight and have a 10 and a half hour flight, get to Santiago at 10.30 and then have to wait around until 4 for the connecting flight to Mendoza but at least that is only 50 minutes. So a very long day for us, not looking forward to it.
IMO it is a lot easier travelling with them when they are smaller than when they get more mobile.
