Update to my 7 mth old eating habits

So last night I tried a couple of new things and it worked! First, even though he is 7 mths, I gave him one of those biter cookies. He loved holding it and eating it! After he chewed on it for about 5 minutes, I started feeding him. Everytime he opened his mouth to eat the cookie, I put a spoonful of food in his mouth. AND - I did try the plain Yobaby yogurt. He LOVED it! It looked thick to me but he just gobbled it up. I have never seen him open his mouth so wide. He even put the cookie aside so he could concentrate on the yogurt.

So now my hope is that this was not just for last night!
