Sir My daughter is 5 months old and she normally used to vomit most of the time when breast fed. When consulted paediatrician abt the same they said it is ok but when you switch to solids, even then also if she vomits then he needs to do some tests. This is what he said. But today my wife gave her cow milk at evening 0600 pm but my daughter took some sips and refused to take anymore milk. After waking up two hours later she vomited heavily. This is the first instance that she vomited heavily. An hour later she again comited. Please give suggestions what could be the probable causes?
