My son did puke a lot, but my hospital provided clothes so I don't know how many I got through. If someone can bring clean ones in each couple of days that would be ok. I would use a muslin under his head, laid over the sheet and tucked in (and did for a few months afterwards!) so I often got away with not having to change the sheets too.
My Oh would bring in snacks and cakes and stuff, to be honest I was eating normally in the evening after a late morning section. I have to say being able to eat Rocky Road at 3am was a good memory of mine.
Peppermint tea will be good for the wind - and there will be wind!!! but better check with a BF expert on the effect of peppermint on milk supply. Midwives had peppermint capsules that we could have.
Shoes without backs will be a must - flip flops for the shower, may as well keep them as slippers too. Bending down to put on shoes was not something I could do easily!
Bring some thick maternity pads for when you're wearing knickers - you won't be until the catheter's out. I was laid on maternity sheets or whatever they're called the first night.
Move as much as you can - if you need to take more painkillers to move then do it - it's better than not taking them and having to lie down. The more you walk about the quicker you'll be on your way!
Do not be afraid to press that bell - you can't move easily and picking up your baby is a bit of a palaver as you can't just reach across. I was a bit naughty in the end, I had a blanket underneath him. I would make sure the cot was touching the bed and I was on the same height, then I would gather the blanket like a hoist and lift him to me. I never let the midwives see me do it- I don't know what they would have said if they did! But to be honest it would take me at least 5 minutes to lower bed, put up back of bed so I could sit up, slide onto feet, walk round bed to baby, pick up baby, come back to other side of bed, struggle back on etc etc etc. This was all because I was too shy to press the button whenever I needed help.
I went home 4 days after the section. I might have been able to go after 3 but I was in the "3rd day blues" and was in pain still. It was quite amazing the change in me on Day 4 - I was moving without too much trouble, all happy and raring to go home!!!
