Re: Pediatrician advice on solids incorrect?
The advice you got is very common, but that doesn't mean it's correct.
A 6 month old baby generally has only 0-4 teeth and isn't getting exposed to lots of sticky sweet foods (e.g. candy, juice, fruits), so it's not like the teeth she has are at great risk for decay. When she's closer to a year, fluoridated water might be an asset in her diet, but it's just not necessary at this point, particularly if you start taking the precaution of wiping baby's teeth down with a clean wet washcloth once per day. Wiping down baby's teeth is also a great way to get her ready for actual toothbrushing, which you probably want to start doing around a year.
Cereals are often recommended as a first food because they are cheap and are fortified with vitamins and minerals. Aside from that, there's nothing to recommend them. They're just pure starch. No protein, no fat. There are lots of foods that are a lot healthier for babies- you can start with veggies, fruits, whole grains, meats... And remember that when a baby starts solids, the quantities will be very small at first! Maybe a teaspoon or two per day, just for fun.
