I started a few weeks before she was 6 mths too and she started well but then went off them completely, so I jsut left it for a few days at a time and would try again. She wasnt really "eating" and enjoying it until about 7 and a half months. It should be a fun time so if you are getting frustrated and he isnt really ready Iwould be inclined to just wait a few days nad try again, but if he still doesnt want it - leave it again for a while! He will eventually be ready and eat heaps!
