We have used a size 1 newborn teat until now as our almost 5 month old has always been the ravenous type and we thought the slow teat might be the best way to get her to take her time and realise she was getting full. She certainly manages to down her 6oz feeds in no time through the tiny hole.
But is there a strong reason to switch to a faster flow?
I am wondering if she is getting attached to the strong sucking action. Perhaps this might also have something to do with her very frequent hiccups. What to do?
