We received an invitation this morning for my cousin's 5th birthday party on 19th June which is 180 miles away from our house. Even if I had this baby today he would be less than 3 weeks old by the time of the party and my family are expecting me to travel up there for the party with a newborn baby and a 17 month old. We would have to do it as a day trip as we can't fit our 2 kids, overnight stuff (including a travel cot) and the pram into our Fiat Punto. They think that I'm being rude by not attending. Would you go?
