My new born baby never sleep at 1 oclock midnight until 8 morning

Remind me of my first child when she was still newborn. She sleeps in the day a lot and she wakes up at night every 3 hrs for feeding. Thereafter, I try to ensure less sleeping in the day, at night wipe down, FM/BM then burp, swaddle, dim light/no light. If she wake up just don't carry or anything and eventually doze off. Her sleeping pattern started to improve. And eventhough still wake up every 3 hrs, she still sleep back.
