Sounds like it could be. I'm not sure how her sleep environment is like, but you can try the following when it's night time:
1) try not to talk to her, as she'll interpret it as playtime. Keep interactions boring and functional eg feed milk, change diaper
2) keep the environment dark and quiet. Use night light or dim lights when feeding or changing diaper.
3) if she's just laying on the bed without fussing or crying, leave her be. Hopefully she dozes off at some pt.
Jiayou. It's really hard when they don't sleep at night.
