My Husband and I are off on Holiday in April for a week to a nieces wedding in mexico. We are going without our almost four year old daughter and her 10 month old baby brother.(flight too long and very costly and to be honest a much needed regrouping for me and the Mr!) Their grandparents will be coming to stay for the week in our house over easter. The problem is I dont know how to tell her and when to tell her....I feel very guilty about it... If she knew we were going to a wedding she would be gutted! She normally loves spending time with her grandparents but recently has become very 'mummy' orientated. Any advice?
