I had my surgery when my kids were little. Yes, you will be able to hold him after surgery but you will need to ask if you can breastfeed him with the medications that you will be on. If there are concerns with that,you may want to pump during that time to keep your production going. At 10+ months he is eating other food so you are no longer the main source and you may want to look at this as the end stage of the weaning that you have already started.
I would strongly encourage you to have live-in help for 1 month at least then regular assistance for as long as you need. Your focus should be healing/recovery from a major surgery and focusing on positive interactions with your little guy and husband. Initially, you will not feel up to being a domestic goddess. Let others do all those tasks.
