Crying , fussiness. One month (2ml once)

My baby is 4 months 8 days old,For the last 3/4 days she has been crying a lot..Earlier she had colic when she was 1 months old..but after 3 months she never had colic pain..she pulls her ear...there is no fever.Feeding is ok..Sha has been coughing very little may be once daily for the last few days .she has laryngomalacia..She is active.. urine output is okay..No fluid coming from ear. She had Bronchiolities earlier..we consulted local paediatrician,she said everything is ok..No mucus in chest..This is not her usual behaviour..Her weight is 5.8 Her birth weight was 2.5 She had low calcium at the time of her birth..we tried to give calcimax but due to its sticky nature she refused to take .May be it was given hardly one month (2ml once)
