Hello XXXXXXX, thanks for writing to us. I went through your query, i feel that your child may have a gastroenteritis
i.e infection of the intestines / or the child may be having lactose intolerance
which is transient, i.e intolerance towards lactose present in the mothers milk. Regarding the cold
, your child might be having an upper respiratory tract infection , may be viral cause in nature. My suggestion is please do not self medicate the child, have a pediatrician
to get the child examined and the medicines to be started in a proper line. Meanwhile keep a watch on the hydration status of the child , watch for breathing difficulties in the child , get a stool examination done for stool routine and stools for reducing substances in the nearby laboratory. Review with your pediatrician. In the query , you have not specifically asked for any particular question, you have told all the symptoms the child is facing currently. So i once again suggest you to get your child examined by a pediatrician. Thank you , hope i have answered your query. Kindly review with us, regards.
