It's not on my actual bday but the most convenient time, given other engagements and weather timing concerns. My mom is really upset with me for not "being there" for my sister. My sister and I have a close relationship; I told her about the trip and she said it sounded awesome. My sister also likes her privacy so I just assumed she would not want me around so soon after birth. As reference, my sister did not meet my own child until a month after he was born. AITA?
OP, work on your boundaries. You are not responsible for your mom''s feelings about this, which don't seem very fair at all. Your mom is looking to you to regulate her emotions which is not very healthy.
You don't have to justify or explain anything to your mom as it doesn't sound like you're doing anything out of line and your sister is O.k. with it too.
Just tell your mom "It's O.K. mom I love you and I'm sure sister will be fine." That's it.
