I have serious mum guilt so please help. Holiday to Disneyland Paris booked for end of June with DS 10, DS 8, DD 3, DSD 11 and DSS 8. However me and prick of exp split last week. No hope of reconciliation as he was having an affair. Text SC's mum to tell her sorry about cancelling holiday for SC but we ended up chatting and it's come about that the mum and me get on really well and so she's going to take exs place so we can give our children the holiday they were promised. However... beautiful DD is about to be diagnosed with ASD and is hard work. When we're out she will try and run away. I often struggle with her in the house. I'm really worried that I'm going to be out of my depth on holiday with three children, one SN, and basically no help. DD is going to be strapped into a pushchair for around 6 hours a day as the older four will be able to access different rides etc. So my AIBU is.....,. AIBU for leaving my DD with my mum and taking her to DLP two weeks later? I feel so guilty and I really don't know what to do. Please help!
