I feel like a bad mother lately, who doesn't know anything and doesn't understand her child. (The baby cries and I can't calm him down. It just won't work at all! I try rocking him, giving him a breastfeed, doing massage... when my husband or my mom take him, he calms down immediately and falls asleep. ? I don't understand what I'm doing wrong.)
