hi its dr vivek
as you told that you had given supplementary food to your child as per guidelines .
baby can be given supplementary food and breast feed upto 2 years of age . your child has little less weight and has excess cry during night this suggest that your child is not getting enough food . second possibility is of abdominal colic
in your child . .
as you have introduce the supplementary food bowel may be some what irregular .
but if your child is lethargic or inactive excess sleeping . then you may proceed for hypothyroidism
