Thank you for your query on Healthcare Magic.
In early month of life infants will sleep more time in the day and night and it may up to 16 to 17 hours per day in divided timings.
In sleep if you try to wake the child, they will become fussy and cry.
As the child is passing hard stools check for proper reconstitution of the feeds.
Colin in infants around 6 weeks is common and it can be managed with Decolic drops in prescribed dose.
But if the child activity is low, cry is poor, and not taking feeds adequately consult the Pediatrician
for the examination as early as possible.
Hope I have answered your query.
