Welcome to Healthcare Magic forum.
Please do not panic.It is a very common problem in infants less than 3_ 5 months to cry
inconsolably due to various reasons like colic, noseblock, inadequate intake etc.
But if he is feeding well during daytime and has adequate weight gain , then please don't worry.The condition will resolve on it's own as he grows up.Till then you may consult his pediatrician
for evaluation and management of colic.Usually antispasmodics like dicyclomine
and digestive drops (neopeptine
, colimex, colicaid etc) may provide relief.
Your milk output is adequate, please do not consider the amount you pump as the usual output, as it may be far less than what your baby sucks.
Try to soothe your baby by rocking or walking with baby carried in upright positon, or try burping him frequently during and after feeds.
Do not stress
yourself as maternal stress further reduces milk output.You may try Lactation
stimulants like Satvarex powder, as prescribed by your doctor if problem persists.
Wishing you & your baby good health.
