my baby keeps stretching and arching backwards. does that mean she has a lot of gas in the stomach?

1. Feed colic drop such as ridwind 2. Tummy massage to ease colic e.g. push your baby's thigh towards the chest. 3. Use anti-colic milk bottles (if feeding from bottle). Brands such as Dr. BROWN which is effective to reduce colic. 4. Swaddle your baby using brand such as swaddleMeUp, as it claimed to help to reduce tummy discomfort.

Yes...this is the sign to look out for colic (gas in the stomach). Baby is unable to expel the gas on their own yet. Normally, you can reduce the gas by doing "bicycle kick" for ur baby or rub oil on her tummy.
