Hi , little Bub is 11 weeks old , and has been formula fed since she was 5 days. We also breast feed but I guess due to milk supply she cries for hunger so I have to top up some formula milk to satisfy her . A few days ago , she had diarrhea , with mucus and blood , she also has flaky and dry skin on her belly. One dr suggested it might be an allergy and wean it off right away . but the other asked me to wean the formula gradually . Since I ended up with a very cranky baby after weaning it all off , I changed the milk from S26 gold to NAN . I hope I did the right thing ? I will be visiting another paed , whom I'm hoping to get real answers from on Monday . Please help if anyone out there has any suggestions and can help .
