Dunno if this will work but I put my baby on sorta a scheduel. If she sleeps during the day I let her take small 30min naps, maby 3 or 4 times, but more than that and she wont go to sleep at night , also, I always give her a warm bath every night at 10:00, then feed her afterwards, that seems to help a bit. But the trick is you have to keep you baby up, it took me 4days to get her to stay up during the day, she would get cranky when I woke her up, and I was really tired myself, lol, but its worth it now to get sleep at night. She'll usually wake up like one time during the night and i'll feed her and shes back to sleep. I hope your little one starts goin to sleep at night! Good luck
