Looks like tribal war paint.
I am not a big stickler on keeping Liam away from sugar. My parents did with me...and I turned out to be a sugar-hog anyways....mmmmmm, candy. I am trying to restrict the amount and the frequency of such treats, but still allowing him to try stuff out. Things with artifical colouring on the other hand are a completely different story. Those I am certainly trying to stay away from. All in all, I think it is most important to teach Liam how to achieve a balanced diet of a variety of healthy foods and to ENJOY himself. Food is not guilt, nor is it a reward or bandaid. Momma's love should not be equivelent to a tastey treat.
