I put it down to bubba just guzzling too quickly for herself, but I think it's becoming more frequent. She stiffens her body, turns red/purple and doesn't breath for what seems like a long time and then screams once she's caught her breath. She's on newborn teats (MAM bottles), but the flow does seem quite quick. I told the HV, who just put it down to her guzzling too quick aswell. It probably is that, but I thought it would have calmed down after 3 weeks of bottle feeding (she's now 6 weeks old). It doesn't happen at every feed, but I would say most. Not much about it on Google, a couple of pages saying it might be a premature baby thing. Can anyone relate?
