You could be my daughter, her husband and I 2 years ago. The three of us took turns holding a Very colicky baby. Have you been to the Pediatrician? There is medicine that could help. Be forewarned tho, this may last 6 months, it did for us. You are probably not being unreasonable, but pumping and getting little sleep is very difficult and her hormones are probably going crazy as well. Just tell yourself to hang in there....it is soooo worth it! Soon this will be over and you will have a great relationship with your child as you will have bonded so well. Good luck and just come vent here when things get rough. Your wife loves you and needs you at this time in the marriage, and again, it won't last forever!
