Hi Saecasm,
I had a huge stroke 4 yrs ago at the age of 33 - 2 weeks after my first child was born. My left arm/hand was & still is completely paralyzed. Raising a child with one wing is extremely difficult!
Some things to think about
:
1. not able to lift him in/out of crib or car seat. Not able to pick him up if he falls. My son was very big (9lbs 12 oz)

, so, it was hard to carry him (which I kinda did like a football) while still keeping my balance.
2. changing a diaper is possible - it just ain't pretty

. (Use your leg to hold his legs up). Good news is you'll get out of changing as many diapers as you would've normally!

Plus, until you've had a chance to practice, someone else will need to fold his laundry
3. You can't play patty-cake or other clapping games. Not the end of the world - you'll find different games.
4. Have to be careful and really pay close attention when he's in the bathtub, as you can't lift him out.
It's really interesting because you're child will learn to 'work with you' more or less. For instance, once my son started walking, he'd back up to me so I could wrap my good arm around his tummy and lift him onto my lap
And, of course, the older they get, the easier it gets

because they can get into and out of their own car seat, and even do up the belt. They can help you do the grocery shopping and even carry a bag! etc. They begin to feel really important when you ask them to help you. You no longer need to change diapers, and so on.
You'll definetely need to ask for help from family, friends, neighbors, or even strangers!
I think the hardest part is emotionally when you see other mommies carrying their child on their hip, and you know you won't be one of them. But, there are thousands of people who raise children just fine with one arm, and we'll just have to be one of them.
One tip that no-one told me about is to use your hip to pin things against a counter/table to hold it (eg to hold a baby bottle while screwing the lid on etc)
I tell my son that my arm is sleeping and that we have to be very gentle with it.
I hope I haven't scared you because it's such a rewarding experience - just different for us. But, you'll learn to adapt so well that you'll even amaze yourself!
