How to deal

So I just had my baby 6 days ago and we came home 2 days ago she is the most calmed and chill baby but I have a 2 year old that I just know how to deal with her sometimes.i pay attention to her all the time keep her involved she gives the bsby kisses but her attitude it's just worse! I can't tell her no cause she'll cry and kick stuff. My husband help me a lot and he takes her everywhere so I can get some rest but idk what I'm gonna go once he goes back to work. Makes me so sad just to think about it and on top of that I wanna cry for everything. Well if you have any advises they're welcome thank you.
