Baby will not sleep!

Ok so my baby has decided that he doesn’t want to go to sleep at night . He’s 7 1/2 weeks old and this has just started . My husband and I are so sleep deprived that we can hardly function. We try to keep him awake as much as possible during the day, but we all know how hard that is to do for a 7 week old . I feel helpless and at a loss. Here is what DOESN’T work:

1. Swaddling

2. Keeling him unswaddled

3. A pacifier

4. A bedtime routine

5. A warm bath

6. Singing to him

7. Rocking him

8. His rock n play

9. A sound machine/white noise

10. Reading a book

11. Walking around with him

He is just wide awake even after he’s eaten and had a diaper change . He just stays awake!

Any other ideas???
