IT'S NOT CIO!!!
IMO, CIO is letting your child cry without you being there comforting. Let's face it, babies cry. I know I held my son helplessly many times while he was crying... offering the boob, walking him around, changing his diaper - NOTHING would settle him. This is NOT CIO! You are doing the best you can to try to comfort your little one and that's what counts.
I have bf'ed my baby in the backseat of the car by leaning over him - I've got a screamer too. It's gotten better over the last couple months as he's now 9 months but it was brutal for the first 6 months or so. I couldn't breastfeed him in the minivan unfortunately so we would either pull over and breastfeed him or drive fast
to try to get there sooner (plus he seemed to be calmer when the car was moving faster - go figure!
: ). I found that it got much better when he got to the age that he could play with toys. We got him a bunch of soft toys and it seemed to help a little. He also seemed to like having a mirror up...
- It WILL get better soon, I promise!
