Ear problems in one and half year baby.

Hi doctors My baby continuously itching his right ear most of time. And left ear too. Keep finger inside ear and keep rolling for till a minute. And I think its a problem over 2 months. But it was not noticeable but for last four to five days I found that he is not able to sleep properly. Sometimes fever occur and loose motions too. And in play time he bend his head on either side and lie on floor on either ear side. Same in night he wakes up in mid night or late night and sit and again lie on bed on putting either ear side on stomach. As I saw trough torch ear is clean no smell and lo liquid. I feel something inside his ears which cause problem because he irritates and starts crying in night or day. And I ask to some relatives they told that breastfeeding while lying cause ear infection and born some bug in ears which irritates. Please help me because he has loose motions too note desire to eat and most serious ear problem.
