My 6 month old has been flailing her free arm around while she eats to the point where she is smacking me in the face through her feeding! I have tried to gently hold her hand and give her things to grab (chewbeads) but she doesn't get the point. I know in a month she will be in a new phase and I can laugh about this, but any suggestions on how to teach her better "breastfeeding manners"?
