Driving UBER/Lyft during Sabbatical

Grade 7 at Intel with TC: 160K. Wife works as a contractor for FAANG and gets little bit and almost ends up losing money as they accrue vacation as they work every month and goes on loss of pay these days due to days taken off with toddler falling sick. Toddler (3yrs) old seems to be falling sick every month (cold, cough and then ultimately ends up ear infection) and with already 3 ear infections this year doc wants to put tubes in the ear to drain mucus if she gets one more. We are not OK with that as kid has to be put in anesthesia. Contemplating on getting my wife to quit her job to take care of the kid so that she can be home and not send the kid to Montessori but that puts a crunch on paying mortgage and bills. I will be taking my sabbatical to spend some time with daughter and posibly drive UBER/Lyft in the evening. To supplement my income, can i drive UBER or Lyft during my Sabbatical? I freaking work 14hrs a day taking night calls with the customer in Asia and Europe in the morning and trying to get out of Intel as there is no end in sight from a growth/pay perspective even though i have been recognized by other teams and the org i am is just political crap. Job search is going slowly (applied and they aren't picking up my resumes) and i am not a SWE and in hardware quality. Daughter is first priority and to mitigate the financial situation I can only think of UBER/Lyft for now to get supplemental income unless i find a better paying job so that my wife can quit working completely and spend time with the kid. We just cannot afford running the home with one income with me working at Intel. I am a USC and there is no issue with respect to immigration/visa stuff. Thanks for hearing out. From a Father to a lovely daughter who is also trying to be a good Husband and one going through a mid life crisis at this point.
