Could it be possible that after your DH had the accident and was so reliant on you and having your DD1 who also was that you felt a little overwhelmed with it all and buy slowly introducing DD to the bottle and then was a way of getting some of yourself back and having less of a demand on you? Just thinking of this while eating my breakie. Sorry if I am way off line.

I could never imagine BF a baby with teeth, it scared me a little, but once teeth came it never crossed my mind to stop. Both my girls self weaned and at early ages so I have not had to think about BF an older baby. I think going to ABA meetings would be great. Maybe write yourself a list of all the reasons why you would like to BF longer and re read it occasionally, if you start going to ABA you might even add to it.

I think that things will be very different for you next time around (if your DH stays safe).
