Stressed single mom! What do I do??

I have 2 kids 6yrs & 9 months I have 100% support from family & their dad takes them every other weekend. I took a LONG break due to covid & now I’m ready to go back to work, Now I’m struggling real bad because idk what hours I should work I need advice if anything. My 6 year old is going back to school so I think the overnight job would work best with his school schedule but everyone tells me it’s a bad idea because baby won’t let me sleep. I feel like I can handle the hours I was never really that type of person that complained if I didn’t get sleep I’m so used to it now.

Job#1 7am-3/4pm 10:45am-4pm only morning hours they have available

Job#2 9pm-6am 3-4 days weekly

Job#3 open hours but stressful job
