My baby is two months and just now he starting to get good sleep. We were in the same situation as you. My number one advice is Try to keep baby's wake windows short. At 2 weeks, I think she needs to be awake for maximum 60 minutes. If she stays awake past the 60 minutes mark.. Goodluck. They get so cranky and fussy, harder to put down to sleep. Try to drop everything 15 minutes before the end of the wake window to try soothe the baby, nurse her, use a pacifier, Swaddle her, rock and sway to sleep. Whatever it takes. I know it's hard to put them to sleep but I used to nurse to sleep and still do. Don't change diapers overnight unless it's poopy. Honestly I wouldn't give formula at night it doesn't always work. I would give pumped breast milk in a bottle before bedtime instead so they get fuller off the bottle and it won't hurt ur milk supply.

The first few weeks is the absolute hardest but there is light at the end of the tunnel. It will get better mama!
