ds has continued to make only small weight gains (2-3 oz wk). Saw consultant yesterday, wants to test for Cystic fybrosis - dh and myself devistated that this may be the problem. Have to wait over a week to get the test done. ds is fine in himself, is on Neocate food due to cow protein intolerance, poo is soft and green but apparently this is normal on Neocate, consultant appeared concerned by this. ds is 10 weeks old and 8lb 3oz. Has anyone else been in this situation. Help!
