None of my family breastfed and a few of my female friends were repulsed by the thought. But my dh's family all breastfed and he was quite keen that I give it a go.
Some things to be aware of.
If it hurts, try different positions and ensure that your whole nipple and aurora are in the baby's mouth. Get the baby to open their mouth very wide before offering the nipple. I used to squeeze mine like a sandwich to ensure he had as much of the breast in there as possible.
The let-down can be a bit sore at first, it kinda makes your toes curl.
This soreness will either go away quickly or in rare cases, slowly. I was one of those who found feeding quite painful because of this. All the midwives and breast feeding counsellors said it must be because I was doing something wrong, so they checked everything and I wasn't doing any out of the ordinary. It was only by talking to lots of other women and coming onto Mumsnet that I realised that for some women it just hurts. Nothing to do with you doing it wrong at all.
Don't be put off by that however, it is bearable and it does eventually ease away. You might not even have any pain.
Once you get the hang of it you will be able to feed just about anywhere. No bottles, no sterilising, no waiting for the milk to warm/cool.
Your family may question how you know that your baby is getting enough. That is because they will have measured their milk in a bottle and upped the feed every few weeks.
Your body knows exactly how much your baby needs. You cannot overfeed a breastfed baby. When your baby has a growth spurt, your body produces more milk to compensate. Your baby will be getting everything they need from your milk and because of this you can delay weaning. A baby should not now be weaned until they are 6 months old, but if you are breastfeeding well you can put this off even later if you want, then you can avoid the endless purees.
Although I'm sure someone will point out that there is such a thing as baby-led weaning now where you just give them food off your plate, lumps and all.
Your breasts will leak from time to time so inest in breast pads. You can express milk if you want to go off somewhere, but wait until you're more confident first.
It really is a joy to breastfeed and strengthens the bond between you and your baby. The first time round your milk will have just dried up. The lady in the bed next to me bottle fed hers and her breasts never leaked so she presumed they didn't have milk in them. But that's not true, everyone is different and whilst mine were leaking whilst pregnant, other people don't have such a problem. Once your baby is latched then your milk will start flowing.
Best of luck!
