Because it feels cruel and it's only been an hour 
She is 21 months and I've tried to cut down gradually but getting nowhere.
She is feeding more than she did as a much younger baby and biting, pinching etc. I am miserable and don't want to continue.
After an awful day yesterday where she followed me around all day looking for 'mi mi, mi mi' I decided I had enough and fed her through the night when she wanted but as of waking up this morning I said no and tried to distract her.
She was very upset for about half an hour but she's had her breakfast now and is a bit better.
I want to be able to play with her, cuddle her, carry her without it always having to lead to a feed.
My mother (who only fed each of us for a few weeks so doesn't have much experience) says it will be fine, she'll forget qucikly etc but I can't help feeling it will upset her and damage our bond.
