This weekend I am taking DD (7months) on the train to visit my parents who live 300 miles away. DS1&2 (5&3) are staying with DH and having a boys weekend involving bbq's and bacon butties. I've done this twice since having DD and have told the boys I am visiting Aunty "X" who is a family friend rather than my parents. This is because DS's love to visit their grandparents and I feel they would be really upset if they knew I was taking DD and leaving them behind. We are all traveling up in the summer hols but I can't take DS1 as he has school and I don't like splitting up DS's as they are so close and have so much fun together. DH wants to tell them the truth as he doesn't like lying to them which I don't either but I really don't want to upset them unnecessarily either. AIBU?
