Hi Doctor, My baby is 56 days old and her weight gain is good. From second week she is having gas problem and crys a lot. We shown to doctor and they told if weight gain is normal, no need to worry. But now a days she is not sleeping properly. Today from morning to night she slept only for 3 hours. And one day she was not slept for whole day. In night she is sleeping for 6 to 7 hours. Is this normal? Very much concerned about her growth both physical and mental.
