Hello doctors, My 6 month old daughter is very much use to sleep from my Mothers hand only. She kind of get cranky if I or my wife tries to take her in arm and try to make her sleep. My mother is not around now for sometime and my baby is giving very hard time in sleeping. She becomes very cranky and after so much efforts and once she is tired she sleeps.But whenever she is sleepy she kind of starts looking for my mother. My heart is breaking out seeing her in this position . is this normal for babies? will her habit change with time? Please suggest. Can baby remember the faces or persons? how much time it take
