A. Sleep Cycle in smaller babies is veryg different and they have a certain pattern initially which becomes regularize at around 6 to 8 mogjnths 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.
