Jealousy with new baby?


My daughter is 18 months and has been the center of attention from everyone since she has been born.. my other little girl was born on Sunday and im worried about how she will act around her new sister. I am also a stay at home mom and my husband works a lot so it is hard for him to help me.. does anyone have any tips on how to make things easier? Has anyone went through this kind of situation because I’m lost and I don’t want my first daughter getting jealous of her new baby sister or thinking she’s not as loved anymore
