Our local sure start centre has a breast feeding club that is run by trained breastfeeding mums, or mums that have breastfed before. It's great
When in community I always encouraged mums to go antenatally to get to know the women who run it and also so they knew what to expect, cos lets face it, it isn't always chocolate and roses!!!
I always try and be very hands off with breastfeeding. I tell the women that they need to find what is comfortable for them and that baby will normally find his/her own way of feeding. I will help position if required (usually post LSCS women who can't move too well), but I always sit with them if they need me to, and I always assure them I'm only a minute away if needed.
With regards to the food, I would advise why they should avoid some foods and explain that in pregnancy we are more at risk of salmonella etc, but I often found women saying things like 'I can't eat any mayo, or tuna'. This often came from articles in newspapers!
I think the biggest no, no is unpasterised food stuffs.
One of the midwives I worked with would advise women to avoid runny eggs, liver, some fish, alcohol, but she would tell them if they were desperatly craving something then a small amount is generally safe. She would always tell them that runny eggs should be the stamped ones that are supposed to be salmonella free.
As for coffee, chocolate, etc she always said again in moderation.
I just think there is a fine line between, healthy advise and too much which will scare them and feel fed up that they can't have this, that and the other.
