Crying baby

Being a mom is difficult. I don't know what to do to make my baby stop crying. I did dancing, singing , feeding , taking to him but it didn't work. Life oh life. Thanks God that my patient works pretty well. I almost dried up. I don't know what his problem right now. Im doin my task while standing and holding rocking him. My mother in law said that maybe he is teething hmmmmm il try to observe well..
