to give foods to a 4 month old? just a hypothetical. i know they don't need it and bm is enough til 6 months or whenever. but what are the reasons that it is bad for them? i always thought it was that the digestive system isn't developed nough yet but hten i heard it's got something to do with the gag and swallow reflexes? is any of that true? and what about when they really watch you eat and are grabbing for things. sometimes i feel bad.
