Not all if I don't find it necessary! Admit it or not, during annual check-ups, with no underlying health problems but just for general and regular appointments, there are these medical practitioners who endorse products for you to try because they are affiliated with a certain brand or product. Not a big deal especially if the product is approved by the FDA and BFAD and tested or proven by the market consumer, but when infact you know that the recommendation is a selling tactic and really don't seem to be vital, don't be afraid not to comply, you know your child well (and a little more customized parenting method won't hurt).
