My 45 days baby cries a lot and also very loud in evening till her night sleep. I consulted with a doctor and she gave medicine for cold only but still my baby is in same position. Is it serious or normal?? Also she sleeps in my lap and when I put her down on bed she gets up just after 5 minutes and cries.

I also feel this is because of colic, and sometimes, even though you may be doing everything right, baby still continues to be in pain and cry. i would say continue massaging your baby's navel area with a paste of heeng and water. do so with a little pressure to ease out any gas buildup. also hold baby in an elevated position while feeding and keep burping at all times. speak to your doc about the best and safest medicine that you can give, as your baby is very young. don't lose heart, as colic surely goes away by the 5th month.
