strange.. i thought ive replied this yesterday lol
crankiness, loss of appetite, fever, diahhrea, drooling etc are all very common during teething though some babies go through it without any problems at all. some baby cant sleep well due to the pain. thats also the reason for crankiness n loss of appetite. you can try giving him teething toy to bite in the day and at night give him those teething soothers cream from pediatrician. DIY teething toy can be simply raw cooled carrot sticks. just cut them up into thick slices so he cant bite it off, then cool in the fridge n give it to him. the hardness n coldness can help him soothe his gums. hope this helps.
