My 7 month old baby started antibiotics yesterday for an ear infection and today he hardly drinks and has no breakfast, is this normal?

It happens indeed when we are sick that we are less hungry. As long as he drinks a little and wets his diapers, we don't worry, we don't want him to get dehydrated, which is more likely if he has a fever. It is very frequent

Welcome

Has baby's general condition improved in the last 3 days? Is he still hydrating well?

It's a pleasure.
