i agree with the above, avoid baby food, not right for them at all.
then the other foods really do lead to a debate, if you were to go on alot of the US forums an said you feed livefood you would not get a nice welcome at all, many in this country do feed a mix of livefood an CGD (repashy or clarks are the better ones) my cresties an mossys get the CGD 3 times a week with livefood fed the rest of the time, you will find with each gecko some prefer differant things, some will prefer there CGD an have the odd live pray now an again or you get some that will only eat livefood
if your botherd about crickets, dubia roaches are a good choice and most geckos love them
fresh pureed fruit should be offerd as well now and again for a treat, i only have one that turns it down
