I do sometimes wonder though with some parents as to why they inflict travel on infants - especially flying. I was on a flight to berlin and an infant no more than six months old was screaming and obviously distraught with the ordeal of flying (air pressure on ears probably) - and this essential journey was inflicted on the poor child (and surrounding passengers) because the parents wanted to go to a heavy metal concert.
Because, you know, it helps get children used to the idea of travelling and how to behave. As well as getting used to other places and cultures (alot of British people would benefit from that right now). Are you saying families shouldn't take holidays together?! Or should we all be hermits and keep out of your way?
Fact is children of a certain age scream when they're not happy in lots of different situations, in spite of the parent(s)' best efforts. Deal with it - you were that age once too.
Holidays always involve travel in some form I'd rather take my 2 and 0 year olds on a long train or plane journey, than on a long car journey, where they are strapped in for long periods (which is also not good for spinal development etc.).
Took them to Germany last year and it was generally fine, except that the two year old point blank refused to sit down and strapped in for landing in Germany no matter what feeding/entertainment/toys were offered (he'd been fantastic up to this point). It literally took me physically restraining his legs for the whole seatbelts on phase, with much screaming. Nothing to do with discomfort, he just didn't want to be strapped into a seat (as is sometimes the case in his pram).
The other flights he's done (including 12 hours each way to Hong Kong) he's been fine.
Thankfully, 95% of people aren't arseholes about it. One guy came up to me after we parked up on the stand with a "Don't worry mate, I've been there myself", which was lovely.
And it was worth it to see him enjoy Miniatur Wunderland.
