hi my baby is 6 weeks old . during feeding he will start crying a lot. again after taking in upright position he settles for some time and again repeats the same. he is passing gas during feeding ..sometimes he settles after passing gas. but sometimes even after passing gas he cries a lot. we are using g neopeptine drops but it is of no use. what is the solution? is it common for a colic baby to cry during feeds??
