Hi redgum
Sounds like you worked really hard to feed your baby; I'm sorry things didn't work out how you wanted.

If you can get on to the ABA about a breastfeeding class, that would be a great start. Or just join and read the book you get. Also, don't be shy about calling the helpline - 1800 686-282 - the counsellors are there to help talk you through any questions you may have.

Being with your baby, and offering the breast lots is a great start. Talk with your carers about what you want - if you want them to be exclusively breastfed, then make sure your carers know. If you have trouble talking with them at all, use another support person as your intermediary (like your partner, or sister, or whoever)

Learning about how breastfeeding works and what is normal for babies is really, really helpful. This is why I recommend the ABA classes or membership. Most mums leave hospital with little to no idea how lactation actually works and also no idea what's normal for babies. If you know these things, you will be well on the way to meeting your goals.

Few pointers.
Babies feed 8-12 times on average. Many feed more frequently than this.
In the first few days, before your milk comes in, you will expect 1 wet nappy per day of life (so, 1 on day 1, 2 on day 2 and so forth) and some poo, changing colour from black toward yellow as the milk comes in
after your milk is in, you expect 4-5 heavy wet nappies (disposable) and 2-3 poos (soft, unformed) or more!
Babies will have short awake times at first, but should have some period of being awake and happy during the day. If they sleep all the time, or are cranky all the time, these are indicators that something may not be right.

Most of the time, if you feed your baby when they want to feed, everything works out.
