My DD is now nearly 29 weeks old and has been exclusively breast-fed. She has also never slept through the night (another story). This evening she was crying on my breast as if she was frustrated re the supply. I tried feeding her in bed. Still no joy and I really would like a good night's sleep (as would DH). So I gave DD a bottle of formula, her first ever. She downed it in less than 5 minutes and smiled at me - a big smile. Now what do I do? I feel guilty. DH doesn't understand. Have I made a mistake? I don't want to give up breast-feeding her. Is this the beginning of a slippery slope or does it mean there will be more milk for her dream-feed? Should I express now? Any suggestions gratefully received, even if it to tell me off and to say don't do that again love if you want to keep on breast-feeding.
