Everything gets ten percent worse every day

She is about 5 and a half weeks old. Every day she cries more, sleeps less, needs more soothing and eats more frequently. How do we stop the trend? Part of me wants to give in and just wear her always until my husband can give me a break to sleep, but part of me also needs some hope to hold onto that one day she’ll sleep in a crib or not scream until she loses her breath. I feel guilty all day because of how unhappy she is. How do you make a baby happy?
