I hope IANBU but just checking.
Background is this, I get on very well with my brother and his wife. Brother is a 'cheeky chappy' with a habit of pushing his luck, (especially with family) but is essentially good-hearted.
SIL had my baby nephew 12 weeks ago and has had to return to work 3 days a week (Thur - Sat) as she runs her own hairdressing salon. My brother sometimes works the odd Saturday and I have told him that 'in a scrape' I will look after my nephew if they can't get anyone else to do it when they are both working. I am almost 6 months pregnant myself and DH and I are pretty busy most weekends getting ready for our own son's arrival (bathrooms being done, decorating etc)so it is not ideal - I have offered it more as a 'last resort' to help them out.
With that in mind, AIBU to be a bit peeved that bro has asked me to babysit my nephew this weekend, when he is NOT working, but is going to watch the football instead?
I am worried that when my baby arrives he is going to be worse and expect me to be happy to look after DN every weekend along with my own son. Do I need to nip it in the bud, and if yes, how?
