Like clockwork

I don't know how mothers do it...most babies start to sleep for longer periods of time by this point (3 weeks) my child seems to sleep less.
From 6-10 last night she was screaming bloody murder-wouldn't eat, had a clean diaper, didn't really have gas....just crying, crying and more crying. It was exhausting.
So after her 4 hour cry session I figured she would sleep well for the rest of the night...WRONG! She slept until about 1 then woke up to eat then thankfully fell back asleep only to wake up at 4 to eat and cry again....its not 4:53 and we are still awake and she is still cranky. I am desperate for sleep.
Jeff is sleeping peacefully in the bedroom as usual and I swear to God if he complains he is tired or bored today I'm going to kill him.

I just don't know what to do for her-she cries when she drinks breast milk, she cries when she is on formula, she has terrible gas/digestive problems-I am at my wits end!!! I NEED sleep-the more I go without sleep the more of a terrible person I become. I don't want to become one of those mothers who is cranky and irritable all the time, but I am slowly becoming one.


And if one more person gives me a suggestion on what worked for their child I am going to SCREAM!!! My child is not your child so what worked for them doesn't automatically work for her get it?
