BLW Day 4: Hello Banana!

Today was supposedly Potato Day but when I checked our supplies, nada. So we gave Von banana instead. (Banana is staple in our household as I am a big fan just like my Papa.)

I've often read about the 3-day rule in introducing food to babies but I guess I am the pasaway. So just to be sure, I googled if the 3-day rule is founded by science. But couldn't find any article clearly saying that one should give same food to baby for 3 days. Others may be practicing that rule, but I guess I will be an exception (LOL). Will just stick with "safe" foods and stay away from potential allergens. I might practice the 3-day rule when introducing allergen suspects.
