Newborn and toddler

So I have a 21 month old daughter Grace and a 6 day old daughter Zoey. Grace has been curious, petting baby and gets excited when she sees her. However she keeps stealing the binky and wanting to suck on it.. she hasnt used on since 15 months.

She also seems to be acting out more, I'm not sure if it's just that she is 2 and has big emotions or is jealous of baby.

Any tips on surviving this phase with 2 under 2??? My husband goes back to work Wednesday and I'm terrified to alone. I'm worried that grace will try to throw a toy at her or kick her. Grace wants to sit on my lap when I feed baby too..
