Mommas I have a question, I give my baby Gerber formula and it takes a long time to desolve completely and I have to shake it so much I get tired and frustrated. I then have to give it time for all the air bubbles to disappear and then feed my baby!! So I thought it would be a good idea to buy a stainless wire mixer that I can put inside the bottle and mix the formula. It works amazingly but was just wondering if it was safe to use it in his bottle. Has anyone ever used one before?? I don't want to keep using it unless I know it's safe.
