Has anyone had to give a supplement to a toddler (not formula, like a weight gain supplement)? My 13-month-old is at the 10th percentile for weight now after a recent illness. That would not be a problem if she had always been petite but she's been declining slightly and then when she got sick she just dropped off. She's not a very good eater.

Anyway, the pediatrician told me to give her Fortini. Haven't bought it yet. Anyone have experience with this situation?
