Should i let her cry it out?

My 2 month old will not sleep hardly I feed her , change her, swaddle her , bounce , rock, jump, twerk ( not really it’s the only thing i don’t do 😂😂) with her to get her to go to sleep and FINALLY goes to sleep I mean open and everything and I lay her down within 2 mins she wakes up wide awake I mean as if nothing happened I have to start alllll over again the other night It was 7am before she actually slept more than 30 mins and then she woke up and stayed awake till 2pm that afternoon then she finally gave in and slept maybe 2-3 hours then up again I’ve talked to her dr and they said It could be different things hard to pin point It without actually seeing her in person but I’ve asked different people that has kids like I’m doing now and different ones said to let her cry It out a lot of there babies would do the same thing they would lay them down and leave and they stopped doing that and some said Cereal just a little bit in her bottle might help her sleep better to So I’m asking should i try the cry It out and give her a little bit of cereal in her milk or what do y’all suggest I’m willing to try anything I don’t want her (and me ) to be miserable and that’s what we are right now please help I want to do what’s right for my baby

Also I’d Ike to add she’s not awake crying all night just wide awake she cry’s whenever I don’t pick her up when she wants she has a paci I give It to her and she settles but starts up again i guess you can say talking and i have a box fan for noise but I’m struggling with her going to sleep and staying asleep also I’m not pushing for her to cry it out or cereal in her bottle I didn’t do that with my first baby I waited a several months before I did that’s just what some has suggested and I doubt she has her days and nights mixed bc I try during the day when’s she a awake sitting her somewhere where she can see light and when she sleeps making It darker I seen that was something to try also
