Thank you for your query,
This is a classical presentation of evening colic
, which presents with excessive crying and decreased oral intake at that time.
It is due to pain in abdomen, nothing to worry it subsides as age grows.
You can give drops like colic aid drops 15 minutes before feeding after the advise of your doctor.
Hold the baby tummy against you shoulder while crying and it will reduce the pain.
You can massage
gently if baby cries with colic.
But if any associated vomitings, loose motions or abdominal distension consult your Pediatrician
Hope I have answered your query.
