My 15 week old DD is showing all the signs of teething, dribbling, chewing her fists, red cheeks and unfortunately disturbed sleep. She has gone from waking once in the night to waking up 3 times - each time I'm offering her a small feed which she is taking and which is sending her back to sleep. Is this the right thing to do? I dont want to get her into the habit of waking for a feed. (She won't take a dummy by the way).
