Do u beat your baby when baby is cranky or keep crying non stop you have tried everything but still no use? I just slap his backside or shake him using both hand holding baby's arm ~ I m suspecting I am having depression~

No you don't beat or shake a baby!!!! what kind of dumb question is that. Babies have no idea why you are hurting them. Babies are learning and trying to communicate. You need to go to your doctor and tell them about your depression and also see a therapist before you really hurt that baby. I can't believe you would even think hitting it shaking a baby/child was ok. No, it's absolutely not ok.
