I'm pretty sure I'm BU and need to get over myself.
DD turns 1 next month. We had her christening recently with a big party which she did great at but was quite overwhelming. For her birthday, I just want to do a normal small tea with cake, immediate family and her godparents (who have a daughter a similar age).
SIL has met DD once (her choice, she is not interested). She didn't come to her Christening because she had a friend's party the night before (it would have been possible to come after if she'd wanted to).
I don't want to invite her and her partner to the tea. DH thinks if we're inviting my sister (who we see at least once a week), we have to invite his. I know it's really petty and childish, but I feel if she couldn't be bothered to come to the christening, I dont want to host her for the birthday. AIBU?
