My dd is 20 weeks old and had been breast fed since birth including expressed milk in a bottle. I exclusively expressed for a couple of weeks in the early days but managed to get her back on the breast eventually so she quite happy switching from bottle and breast. We have just got through 2 teeth coming through but i think there are more on the way! I have been bitten 10 times today and she is refusing bottle! I am feeling really down at the moment and have just bought a carton of actimil (not that she is drinking from bottle ) don't really know what I'm asking to be honest , anyone with hints to stop them biting?
