hi my two years five months baby boy is very active n till now he is not fully understood everything that what to do or not.but the problem is since last ten fifteen days he started biteing other children while playing. I mostly say him not to do like this but he is unable to control himself. like he is on slide n the front child is slow than him then my boy is biteing the front boy. sometimes in excitement he do biteing to his friend or due to other reason may be too. m very much worried how to stop it?? in this age do babies do like this?? he is not harmful but sometimes he becomes impatient n biteing or in excitement he do like this. when he will stop?? do I should not allow him to play with children now?? but always he is not doing like this but at certain monent it happen. please suggest
