To start with I second everyone else's suggestions of drink, book, magazine, nibbles (obviously cake fruit), telephones, remote and laptop and raise my own suggestions of a foot stool and lots of comfy cushions.
There isn't much you can't do whilst feeding - low high points for me have included nappy changing older sibling, hanging out the washing and going to the loo needs must and all . The last one is not something I'm proud of and certainly wouldn't do in a public toilet but with a new baby who needs feeding NOW and weak bladder that needs emptying NOW you find interesting convergences of experience IFYSWIM.
Breastfeeding is a skill that can take some time to get the hang of as both you and baby are first timers at it but when it clicks you can do it in the funniest of places and doing the funniest things. Though it's not compulsory to do so
I've breastfed 3 children for a cumulative total of 7 years so I've had a LOT of experience and practise so please don't be put off if you don't find yourself loading the washing machine mid feed on day 3!
On the feeding in bed front if you do a little prep work before it pays off massively.
-The part of the bed baby is going to be on needs to have a bed rail/guard or barrier of some sort (I have the cot attached to our bed frame) so baby can't roll out.
-Lie on your side with your arm raised and your knees drawn up so you make cradle shape with your body. Baby feeds on their side and lies in the space between your arm and knees. You can feed from the other side by shuffling back from baby and tilting your upper body so that the upper breast is now occupying the space the lower one was previously.
-I have DD3 on her own sheet and when she was tiny I apple pie'd her bedding (use a cot sheet and baby sleeps on the top part of it with the bottom flipped up to cover them -they can't wriggle down or kick of the sheet) Now she's older she's in a gro-bag but still on her own sheet. This makes it easier to transfer her in to her cot once she is asleep as there is no risk of 'cold sheet syndrome' waking baby up.
-The fundamental rules of co-sleeping apply even if you do not intend to sleep next to baby but just feed (it's so easy to fall asleep feeding and if you make the area safe in advance you won't have to worry if you do succumb):-
No consuming alcohol/drugs or meds that make you sleepy or difficult to rowse.
No co-sleeping if anyone is a smoker (even if it is your partner and they smoke outside).
No putting baby under duvet/adults bedding.
No putting baby in between mum & dad (we have done that with DC3 but we don't go to sleep with her in between us but move her to her cot once she is asleep).
No co-sleeping if you are excessively tired (I took that to mean no co-sleeping if you were falling asleep on your feet not if you were just normally tired)
Don't put baby on a pillow topped mattress or memory foam mattress as the baby can 'sink' into them.
Sorry for the epic novel on co-sleeping I do prattle on so.
