Can I just add to the excellent advice given here by headfairy and hairymelons and others, - get help BEFORE you give birth, go and make contact with the local breastfeeding support group, it does make a difference to have support.
I have breastfed all three of my children, the first was a nightmare, tongue-tie (not found until he was a couple of weeks old), given loads no unhelpful help in hospital where they forced my sons head towards the boob holding onto where he had bruising from the vontuse..... the list can go on, however I visited a breastfeeding councellor and went to breastfeeding support groups and too it literally one feed at a time. I even had problems with the health visitor forcing my dh to go a buy bottle and formula and bottle feed him at a week old, just because she said so (she stood and watched while we bottle fed him) - Turned out he was allergic to the formula milk and it caused us more problems than ever. I did not bond instantly with my first child, it was very difficult and I did not feel like he was mine for several months.
Anyway having my second child, was completely different, she fed within minutes of being born, like a complete pro. Nothing to do with me, just the way it was.
When I got to my third child I complacently thought , I know what I am doing here, but oh-no. This was not a natural feeder, I had difficulties culminating in getting mastitis and landing in hospital when he was 11 days old. But I pursevered, called up all my old breastfeeding support contacts, and managed to continue feeding him, he lasted the longest of my children, and was bf until he was 20 months old.
Breastfeeding is brillliant if you can pursevere with it.
Just one point - if you don't get any milk out while expressing - that is not unusual, I found it very difficult Babies are much more effective than any pump, so dont get fooled thinking that i have no milk coming out therefore i cant breastfeed. I never needed breastpads, I never leaked, I could never handsqueeze any milk out - but I was very able to breastfeed.
I hope you all get to enjoy the easiness of breastfeeding.
