My 3weeks baby boy is not sleeping properly he is taking only 2 naps in evening and staying awake all the time should i worry about that?

A. Sleep Cycle in smaller babies is very different and they have a certain pattern initially which becomhjes regularize at around 6 to 8 months of age and if the baby is comfortable with no irritability because of infantile colic nasal blockage any regurgitation etc you should not worry just give a comfortable position to the baby and no medicine is required.
