My older brother asked me a couple of months ago to have my nephew (2) on August bank holiday for what I assumed was a night. He and his wife are attending a wedding and will be camping due to cost of a hotel room. He said about a week ago it is 3 nights and 4 days. I live in a 2 bed flat with my son (13) and husband. I was surprised by the length of time but don’t like to say no to my family. My son has asd and when my nephew is around doesn’t really leave his room, due to not feeling comfortable with a little one around. I also had my baby daughter die just over 5 years ago and have had 2 miscarriages since. I had my nephew for 2 nights a month ago and found it very hard emotionally, he is lovely but almost a reminder of what I don’t have especially at bedtime when I cuddle up for bedtime stories. I have grief induced anxiety and I don’t want to look after my nephew for that long as my anxiety is getting worse just thinking about it. I don’t want to let my brother down , but he has never looked after my son his whole life, so don’t think he can get annoyed if I say I can’t do it now. I don’t see my brother very often only for family occasions or if he wants me to look after my nephew. Am I in the wrong if I say I can’t look after him now?
