This is a photo of my son, trying out some bread with herbs made at a gardening workshop. Once children get into growing things and tasting them, they become not only keen gardeners but less fussy eaters. Children are very tactile creatures, observing, tasting, smelling any thing they can. I was surprised to see my son trying out the flavours of different herbs. Last week, he went to a pizza making party and told me he put mushrooms in his pizza which he used to hate in the past. The peer pressure of other children also helps!
So take your children gardening, and if it is safe, let them feel and taste herbs. It will make them good eaters for the rest of their lives.
