What did I get myself into?

I’m currently 24 weeks with my second and they were very planned. I have a 3 year old who was born after years of infertility and is the worse sleeper. Oh. My. GOD. She is great during the day but at night she turns into a hyena and SCREAMS. I have placenta previa and placenta accreta this pregnancy. She wants me to pick her up or hold her in her rocker. I’m only 24 weeks but it’s getting hard. I’m exhausted all the time. I’m losing my patience. I feel terrible about it. My husband has been amazing and so helpful.

How am I going to have a newborn who won’t sleep and a toddler who is going to scream them up when they do.
