Hi,
My daughter is now 14 months old (today!) and we're nursing fine, but I'm still curious about what the cause of her difficult behavior with nursing in her first few weeks of life.
Starting from the very first time Karen latched on, everything would be fine for a few minutes, but then after maybe 30 seconds to 5 minutes she'd throw her upper arm forward into my chest. Since her suck at the beginning wasn't as strong as her arm, she would pop off and get frustrated, making it very difficult to relatch.
We got through this in time. Every single time I nursed her in the first few weeks, however, would require someone to hold her upper arm to prevent her from pushing it forward. After about 2 weeks, I got comfortable enough with nursing that I could hold the arm myself, but before that I needed help from another person.
After 3-4 weeks it stopped being much of a problem because her latch got stronger than her arms. I stopped noticing her doing it at all after ~2 months. I guess she got out of the habit.
Karen's birth was fast: My water broke at about 8 am one day, but my contractions didn't begin for another 12 hours. Karen was born after 5.5 hours of contractions, 20 minutes of that pushing. We got to the hospital about 20 minutes before she was born -- yes, that means I was pushing in the hallway. No meds at any point. She was born with a 4 cm lump on the side of her head, which the midwife said meant that I'd been dialated to 4 cm for a while (I'm guessing a week) and that showed where her head had been pushed up against the cirvex. I also struggled with flat nipples -- I pumped for a minute or so before attempting a latch between the time my milk came in (~3 days pp) and about 8 days pp. I'd pump just long enough to draw out the nipple.
Anyone heard of this behavior? Any clues to what caused this? I've never seen any description of this in books on getting started. At this point I'm mostly curious.
