Anyone here with a 6 week old baby?

What's their day like and night? It depends on the day but my baby naps for 1.5 hrs. At night her longest stretch is 2.5hrs and I'm so exhausted. Any tips or advice? We don't really have a night routine for her Coz it always depends what time she goes down to sleep Coz her feed depends on when she wakes up from her naps
