I have a 5 week old baby girl and she cries uncontrollably, she screams and cries for almost 5-6 hours every night. I am really concerned and dont know how to deal with the situation. We have seen the paediatrician 5-6 times for the same reason but no satisfactory result yet. We have tried changing forumla, gave zantac but nothing seems to work . Only thing that seems to comfort her a little bit ( last two nights even this didnt work - ) was carrying her on arm- belly pressed against arm.I have few questions -
1) How do I know if its acid reflux or colic?
2) Does crying for so long nonstop cause any health problems for the baby? I am very tensed about this thing because I was told it could be colic and it goes away and all that, but what happens to the baby if she goes on crying nonstop for such a long time?????Does here speech or voice get affected or breathing affected?????

Please help, any advice appreciated...thanks!
