Sis is getting married next year and wants to go wedding dress shopping in half term. Unfortunately DH is working that week 9 a.m. till 10 p.m. Mon - Sat and we have a trip planned on the Sunday she is here which we cannot change. I have three children aged 8, 6 and 16 months. Sis said to just bring them - it will just be a couple of hours. The 8 and 6 year old i could plug into something but the baby? Shes at that destroy stage and i doubt the fancy bridal shop will be happy with a whirling dervish pulling dresses off hangers. Shes also just dropped her day time nap. No babysitters - my mam who usually helps will be dress shopping too. I explained to my sis and wished her a lovely time. Now she is complaining to my mum i am making up excuses to not be part of the wedding and is apparently very hurt. AIBU?
