If on breastmilk give rid wind together with breast milk, Give ru yi oil and massage colic massage periodically. Changed bottle to MAM anti colic bottle. Keep baby tummy warm by giving her long pants over romper and socks too.
Give rid wind, given by polyclinic too. So it definitely safe. Or change your bottle to dr brown, it's help a lot with colic too. If mummy is latching, certain food like broccoli cause colic too, so try to cut down.
