My Daughter is 20 months old. During night time sleep she wakes up every 3 hours of sleep. During cry she rejects to take anything and cries for 30 mins to one hour. Finally after having some milk she slowly gets into sleep. Whenever she starts crying. She makes very high pitch noise. We worry a lot that time. Is she facing any vitamin deficiency. Or is she misses my in-laws from where we recently brought to a new home. Any best pediatrician near Nallagandla, Hyderabad.
