I've been asked to talk to the latest batch of mum to be about breastfeeding. Ds has just weaned at 15 months, and according to the mw who runs our breastfeeding group I'm an expert 
So far i reckon:
it's the same amount of work as Ffs but all the hard stuff is in the first 4-6 months
formula isn't poison so don't feel guilty if you need to give it, for your own physical or mental health as much as your baby's
breastfeeding is nature's way of telling you to sit and rest after birth. you have achieved something by keeping your baby fed, if you manage dressed with a hot meal on the table you're superman
anything else?
