Newborn is super gassy

Christen
My poor little baby is super gassy and won't sleep. My pediatrician recommended mylicon drops but the dosage on the box says "under 2 years old" my baby is only 1 week. 
Has anyone used mylicon drops for their newborn? If so, how much did you give your little one? 
Ps- if anyone has any other remedies please let me know!
