My husband's brother and his wife have recently had a very sweet little boy. He's now 3 months old.
My brother in law works full time and my sister in law is a stay at home first time mum, although she was trying to find her feet in her chosen career before she became pregnant.
Since having their little boy she has been offered work experience opportunities here and there (usually a week or so at a time). She is very insistent on doing this even though it's unpaid and instead of arranging more formal childcare she keeps asking other family members at very short notice to take care of their baby. Her husband has used up his holiday allowance so he can't take any more time off himself.
She's just been asked to work next week when I have some leave booked for myself and I'm finding I'm keeping my time off a secret from them so that they don't ask me to help. AIBU and selfish? I think I'm struggling to understand why she keeps wanting to leave her baby with other people so frequently when he's still so little.
