How to adjust to life with newborn???

Elisa
I've been fortunate enough to have my mother-in-law help me for the first week pp and my mom will be here until my son is 3 weeks (he 2 weeks today). My question is: how does everyone manage their schedules with a newborn? I am a ftm and already I'm worried about how I'll feed myself or just do basic things since I've had so much help! I don't know what I'm going to do once my mom leaves. I have a very supportive husband but he does work full time as well. Just wondering what tips have worked for anyone else.
And also, when did your baby start sleeping longer throughout the night???
