I bf'd dd whilst in hospital last time round then by day five was changing to ff as I utterly hated bfing.
Im now expecting dc2 and planned on taking a few ready made cartons into the hospital for the baby but, having not done this at hopital before, im not sure how I go about washing and sterilising the bottles between feeds.
I bf both dc but the hospital provided little disposable bottles pre-made with SMA gold for ff mums. I haven't been in a mat ward for 6 yrs now though but I imagine its still the same set up. No idea if they actually provide different brands though.
You need to ask your hospital. A lot don't now provide formula for ffing mums and you are right you would need to take your own. They vary quite a lot on set up for bottles, etc though, so you need to ask your specific hospital.
Yes, if your hospital don't provide ready to feed bottles then one of those starter packs with 48 hours worth of tiny bottles is your best bet. They are not cheap but they are sterile and disposable and would be so much easier for you than trying to make up powdered feeds in hospital
