Colic and gas
Most babies experience some gas pains peaking around 6 weeks of age, most of the symptoms are gone by 12 weeks.
Babies will be uncomfortable, fussy and tend to draw their legs up. It is painful for them.
Look at possible causes before trying to "cure" it.
Is the baby crying
and swallowing air?
Is there something in your diet
or are you feeding
something else to the baby?
