My 9 month old has been mix bottle breast fed since she was a few weeks old (all breast milk) When we started solids at 6months we found she had a mild milk allergy which meant she couldnt have normal formula milk or cows milk so she has been prescribed wysoy. I started mixing it into her bottle which she has before bed (ie 1/2 and 1/2 with breast milk) gradually increasing the amount of wysoy until she was solely on wysoy. She was drinking it fine no issues so then i tried changing a breast feed for a bottle of wysoy and again she seemed to tolerate this for a day or so then all of a sudden she is now refusing all bottles whether it be breastmilk or wysoy. she drinks water resonably well from a sippy cup so i tried milk in that but she then refuses the cup. bow she is back to full breast feeds which she hasnt dont for about 5 months. but now she has teeth and she bites when frustrated and i dont think my milk supply is sufficient as she sucks so hard it makes my nipples bleed. help please i dont know what to do now. i have 3 months before i start back at work where breastfeeding wont be an option as i will leave before she wakes and be home after bedtime.
