Two under two

I need some advice please lol or answers

My son just turned one and we are expecting a baby girl in one month. I’m very worried about how the dynamic is going to be. Will he get jealous and sad? Will either of them get any sleep?

I also haven’t crib trained my one year old but I want to because I want them both to sleep on their own. Will it be impossible? What do I do in regards to where they sleep??
