My son is 2 and a half yrs now .. he is very picky and still nursing !?

ok first off just stop with the nursing. let him cry himself to sleep. let him learn the hard way. second if hes picky hes picky. make what ever it is your gonna be eating. let him pout and cry all he wants. if hes hungry enough he'll eat it and try new things that way. its harsh but it works
