I'm sitting in SCN right now.. Next to my baby is a little one alternating bottle and boob 3:1. Tube feeds also as she gets very tired. Loads of babies and nurses are very encouraging for ALL mums to attempt bfing. (Apart from one or two witches but you know they're loonies as soon as you talk to them.)
As long as you're happy to stick it out and keep expressing you'll be fine. Just grab a breastfeeding brochure and kangaroo care brochure and leave them on your babies drawer in SCN. They'll be very supportive as long as you're not leaving your baby hungry. I have sat in here at 3am the last few nights listening to a baby scream from hunger while the mum sends down 3mls a time.. It sounds horribly upset she finally agreed to topup aptamil formula feeds yesterday and its settled and happy all night now. Bottles aren't BAD.. Boob is just better.
