totally agree with the above post - in addition try boiling a little white fish (without stating the obvious check and check again for bones) or chicken, give a tiny, tiny amount - if this stays down repeat in an hour then gradually add a little boiled rice then aim for about five tiny, tiny meals per day. Of course it is possible the vomitting is unconnected with the ear infection (although unlikely) in which case the general rule is to starve for 24 hours then start with the food as above. Good luck and keep us posted.
