I was told your milk can take a couple of days to come in so I doubt you’d need to take a pump to the hospital. I don’t think they recommend pumping straight away either
Personally I wouldn’t worry about a pump for now, just wait to see if you want/need one. I BF for a year first time round and bought a pump that I used max 3 times. In terms of what you need in first 48 hours - NIPPLE CREAM! No one told me this so I had to send my other half out on a desperate dash 🤣 put on after every feed because once you get blisters it is very sore (they do soon pass and it’s fine again). I found Lansinoh good for day to day but the Bert’s bees one for a quick recovery if needed xx
Hospitals usually have medical grace pumps there if you end up needing to use one so I wouldn't buy a pump until you really need one. Like others have said, your milk can take a few days to come in too so likely won't need a pump.
I wouldn’t worry about having one straight away, get established with breastfeeding first. I ordered one when my first little girl was about 10 days old. I also got told off by my health visitor for introducing a bottle before baby was 6 weeks old as i could’ve nipple confused her 🤷🏻♀️ I had no idea that was even a thing so maybe speak to your midwife and see if she can advise you on that too! Good luck with your breastfeeding journey!! Xx
