hopeful - I am so sorry to read of your disappointment. Like janeainsworth, my grandchildren live in the States, and it can be really difficult at times to maintain an up-beat and positive attitude. Ana makes some really good points. Christmas would be lovely, but it is probably the most expensive time to travel, so earlier or even a little later might be better.
I didn't see my granddaughter until she was 6 months old, and it was a delight. I didn't feel I had missed anything at all and at that age they are very responsive.
I've just spent a crazy 10 mins. on Google Hangout (an alternative to skype) - and it was lovely just to see their (very grubby) faces!
I try not to feel resentment against the big Italian family that all live close by - but I must admit there are times it creeps in! I try to maintain the attitude that it is as it is and know my grandchildren are lucky to have them around.
Take care
