My 2month old doesn’t like to sleep. HELP!

So my baby is a week shy of 2 mos and we are making almost no sleep progress at night. She stays up and parties at night (by parties I mean cries every 15 minutes because she either is gassy or wants to be held) we’re having to supplement with formula because I don’t make enough milk so far we’ve done gentle similac, and now enfamil genteleese. During the day we’re making sure she does tummy time 2 times to try and tire her out. But she still naps almost all day and sleeps like maybe an hour or two at night. I really need some mommy think tank help on this! How can I make my little girl sleep at night?

Thanks in advance!
