I swear all my child does is cry!! how did you handle this and keep sane?

It sounds like colic, however it took 4 months for my daughter to get diagnosed with it and then it lasted til she was 1 year old. I found out from the start she loved music and for some reason she liked hard rock music, another thing that helped was she loved her vibrating chair, they say this is good and soothing for colic babies, it also helps at nite if you are tired and she is awake, u can place her in the chair and rock her, this way u are still attentive to her but u can rest a little bit at the same time. we also used infant gas mylanta drops that seemed to help and switched her formula to soy formula as its supposed to be gentler on a baby's stomach or else there is gentle formula with a whey protein. Also warm baths seem to help her as well
