Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
loose motion in your child that is lasting since 1 month and started after giving cow's milk can be probably due to Milk Intolerance..
Other common cause can be
stomach infection leading to
Gastroenteritis..
For confirmation of the exact cause of the loose motions you need to consult a Paediatrician and get him evaluated and he can do a thorough clinical examination and advise investigations like Stool culture and blood tests to confirm the cause and treatment can be done accordingly..
As of now you can give him more of oral rehydration salts by dissolving in water to prevent
dehydration..
You can give him banana, multigrain bread, cereals, rice and yoghurt in diet..
Give him sufficient water..
Once he gets diagnosed for the exact cause of loose motions if there is infection antibiotics will be advised..
If cow milk is the culprit you can be advised to stop feeding him with the same and formula milk can be advised..
Hope this information helps..
Thanks and regards.
