Woo hoo. That is so great. It must be a relief to see some normal poop for a change. Bananas are very good for the digestive system too. When I give Tyler banana, I either give him half a banana to hold in his hand and eat, or just cut it into slices and let him pick the pieces up on his own, he loves it like that. Bananas here at the moment cost about $2 each, not sure how much you pay for them, but Tyler is only allowed a little bit each day so they last longer.
At six months I think we only gave solids twice a day. I think about 2-4 tablespoons was about what he ate. Have to be careful not to fill them up too much otherwise they wont want their bottles. Hope the solutabs start working soon and those perfect poops keep on coming!
