Mom going out of town

ma

So my mom and brother are going to N.C. to visit my older sister and her baby she had in August for Christmas, I’m having my baby Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and the only way she’s canceling is if i have a emergency-_- she was there for my sister when she had her baby but isn’t going to be there for me ..she also didn’t even offer to buy the crib or car seat like how she did for my sister..I just feel a little weird like she’s picking favorites or something..
