Hope he is on exclusive breast feeds. Exclusive breast feeding till 6 months of age is the best for your baby.
For his gas problem- burp him after each feeds till he belches out the air.
And as a part of the routine massage
, add these strokes to his tummy
- circular strokes around his belly button - strokes in the form of inverted L starting from right lower end to right upper end and then to left upper end - strokes in the form of inverted U starting from left lower end, go up and then come down to right lower end.
You may use olive oil/ coconut oil for massage.
Also when he cries, try to keep a warm towel on his tummy.
You may also see a Pediatrician
and get medications like colicaid/ colimex prescribed. These will help in his colic.
Colic and gas problems will gradually come down as your baby grows and intestines mature (by around 4 months).
Hope my answer helps you.
Wish your baby good health.
