Is it too late to Sleep train?

so I sleep trained my lo when she was 11 months and it was working. Then we moved in with my parents and then moved into a new house and now she’s 18 months and still wakes up at night and only wants to be in our bed. She falls asleep and I bring her back to her crib. She will cry, yell, and whine. Sometimes throw up from crying so hard. She also won’t nap without a car ride when she isn’t at daycare🤦🏻‍♀️🤦🏻‍♀️

Is it too late to sleep train .. again?

Please help her aka me!
