DD is 5 weeks old and EBF. She has always tended to feed for long periods, usually about a hour but will go 3-4hrs between feeds. Over the past coup;e of days she has spent up to 2hrs on some feeds. Is this ok? Yesterday my mum was here and mentioned someone she knows whose baby fed for 1-2hrs at a time because she wasn't producing enough milk as the baby got older. Is this likely to be the case? I got her weighed last week and HV didn't seem concerned by her weight gain and said to get it checked again in 2 weeks
