I HATE that.... i have so many friends whose kids are on drugs at the drop of a hat! The only non-motrin/tylenol/nose-unclogging meds either of my kids have ever taken (now remember, this is in 4.5 collective years of life): Zach had antibiotics once, for a high, long-lasting and unexplained fever. Once they got the blood work back and found it was viral, they stopped the meds. Sarah's been on and off Zyrtec (on for a bit, and i found it wasn't helping with the allergies so we stopped, but now we're hoping it--in conjunction with something called rhinocort--will help clear up her cute little ears to prevent the necessity for tubes. I don't think it will work, but we'll find out next week). That's IT!! Then there are kids I know who are Sarah's age and put on antibiotics at the first sign of a sniffle--not because of parents requesting, but because of doctors offering.
I'm SO glad I go to a doctor who not only DOESN'T specifically offer meds unless needed, but tells parents who ask that it's not necessary and won't help. It's important to find someone who shares your philosophy. Failing that, at least find one who respects your philosophy.

If Sylvia's doctor was really pushing the formula (And from what you've said, it doesn't seem that she's having any major feeding problems, so what's the need?) and/or drugs, you're right to find someone who makes you feel more comfortable.

Now I'll get off my soapbox :)
