Adjusting to 2 kids

I just had my second daughter a week ago. I have a 2 year old and so far she’s just kind of ignoring her sister which I’m fine with. She’s adjusting pretty well all things considered. My husband only has 3 weeks home with us and then he’s back to work. My question is how did you adjust to having two kids? Any tips for me for my first couple weeks solo with them? I’ll be home full time until I go back to work in 4-6 months so any help or advice would be appreciated!
