Freaking out!

Hi, so I’m about 22 weeks pregnant with my second baby , this time it’s a boy. I have a 16 month old daughter. I am just getting soo worried about how I’m going to deal with two babies both needing my attention at once. I do coparent with my daughters dad, but she does not stay the night there. I just feel like my daughter is going to be super jealous and feel abandoned because there’s a new baby. I know I will give them both the proper amount of love and attention but I’m just getting nervous. I guess I just need some advice or encouragement. My daughter will be 20 months when my son is born..
