vix. Its so hard having a difficult baby. DD2 was like that. She was colicy with slight reflux. Life was hell for the first 10 weeks. She refused to settle before 3am for the first few weeks. Have you tried some infacol c ( wind drops), or the brauers (sp?) colic releif? You can also give panadol if you think she needs it. I gave up bfing at 4 weeks thinking FF would help DD2, but it didn't do a thing. Maybe it will for you though
Have you tried co sleeping? That was the only thing that saved me. I never co slept with DD1, but there was no other way with DD2. Maybe give it a go if you haven't already. I used to pace the loungeroom for hours on end with her in a sling, trying to get her to suck a dummy. I'm so glad I've only had one like that... so far!

Geez, better get these girls up for school. DH is back at work today, first day going it alone...
