Beautiful baby!
My first baby was a cryer. She had colic, some things to try are:
a bottle of warm water
play some soothing music, and hold her close and slow dance.
gas drops
swaddle her real tight, hold her close across your chest and sway from side to side
warm a baby blanket in the microwave, or dryer, make sure its not too hot, and swaddle her
But mostly just hold her tight and sing or rock or sway, whatever works
I did let her sleep with me, because I would rock or sway her to sleep, but as soon as she touched the crib mattress she was awake. I also spent many nights in the rocker recliner. And nap when she naps, the housework can wait.
Don't give up, she will grow out of the colic. I remember sitting on the bed with her and crying to my husband "I can't take it anymore", but we just kept trying everything , but with colic, you can't get rid of it, you just have to comfort her untill she outgrows it.
I would try to feed more often during the day, and make sure she is not over stimulated before bedtime.
Watch what you eat and drink,drink,drink, lots of water.
At least 10 minutes on each breast at each feeding is best, and make sure you start with the one you finished on at next feeeding.
None of my babies slept on their backs, I would use rolled up baby blankets to prop them on their sides, and would rotate which side I layed them on, never had that ugly flat head thing going on, and always made sure their ears weren't folded. (beautiful flat ears, and round headed babies). When they were able to lift their head and turn it, then I would let them sleep on their stomachs.
I believe in a good chiropractor too, never took my babies, because I never learned about it till they were older, but considering being scrunched up in the womb and the twists and turns they go thru during childbirth, I would think somethings got moved out of place.
Good luck with your little darling, and accept all help that is offered from family and firends, try to get your rest, eat right and love every moment because they grow faster than you will ever imagine.
btw, my colicky baby girl is now 14 years old.
OH, and not all babies you have will be the same, my last baby slept through the night the first day we came home from the hospital. I had to get up anyways to express my milk cause I would get so full it would hurt..
