Hi there, I too exclusively pumped from the beginning since both my babies were premature and in ICU when they were born. Colostrum is best extracted manually into a syringe (without the needle of course) If you stay at the public hospital the nurses will be able to show you how to do this. If you go private, you may need a lactation consultant to come in and show you. The first time around, I found it quite painful to manually extract the milk. Second time around it was tolerable. I switched to a pump when my milk came in - around 4 days after birth.
For my elder son, I was able to exclusively pump for 6mths until solids but for my 2nd, I have struggled with finding time to pump and started to combination feed EBM and Formula at 4mths.
Although pumping sounds ideal, the truth is, it's like having another baby to feed. Your life with a newborn - already taking 10-12hrs of feeds in a 24hr cycle, time is precious and if you then have to spend another 8-10hrs pumping, you don't really get any sleep. For my elder son, I was pumping 10 times a day for 45mins to meet his daily intake. For my 2nd, I was able to go down to 4-6 1hr pumps to meet his intake. Then you also have to sterilize bottles...Like someone said above, it's definitely a challenge and if I could have, I would definitely have breastfed. given there are also challenges with breast feeding, I am told that all the effort and pain you go through the first few months is worth it in the end. Oh, just to also let you know, pumping itself is not a very pleasant experience. You have to massage your boobs the entire time to help the milk come out and your arms, hands and fingers will be sore. the first time around, my nipples were not able to take the pump and I cracked and bled for the first few months. 2nd time around, they were tough already so that didn't happen.
In the end, if you choose to EP, make sure you have supportive people around you to encourage you to stick with it without making you feel guilty if you choose to stop. It's very very difficult to force yourself to get up at 3am to pump when you just put the baby down at 12am.
Good luck!!
